A reaction has a specific rate constant of 0.002/hr at 27 C. The initial concentration of 10M will have decreased to 10% of the original value at the end of 230 hrs at 47 C. What is the rate constant at 47 C?
Answers
The rate constant at 47°C is 0.0146/hr.
First, we need to find the activation energy (Ea). We know that after 230 hours at 47°C, the concentration has decreased to 10% of its original value (1M). Now, we can plug this value into the Arrhenius equation to find the rate constant at 47°C. However, we do not have enough information to calculate the activation energy (Ea) or the pre-exponential factor (A) in the equation. Therefore, it is not possible to accurately determine the rate constant at 47°C using the given information alone.
We can use the Arrhenius equation to find the rate constant at 47 C, given the rate constant at 27 C:
k2 = k1 * e^[(Ea/R) * ((1/T2) - (1/T1))]
k2 = k1 * e^[(Ea/R) * ((1/320) - (1/300))]
Now we can plug in the values we know:
k1 = 0.002/hr
T1 = 300 K
T2 = 320 K
k2 = 0.002 * e^[(Ea/R) * ((1/320) - (1/300))]
We still need to find the concentration at the end of 230 hours at 47 C, so we can use the first-order integrated rate law:
ln([A]/[A]0) = -kt
t = ln([A]0/[A]) / k
t = ln(10/100) / k
t = -2.303 / k
t = 230 hours
Now we can plug in the values we know:
[A] = 0.1 [A]0 = 1 M
t = 230 hours
ln(0.1/1) = -k * 230
-2.303 = -k * 230
k = 0.01/23.03
k = 0.000434/hr
Now we can plug in this value for k2 in the Arrhenius equation:
k2 = 0.002 * e^[(Ea/R) * ((1/320) - (1/300))]
0.000434 = 0.002 * e^[(Ea/R) * ((1/320) - (1/300))]
ln(0.000434/0.002) = (Ea/R) * ((1/320) - (1/300))
-1.355 = (Ea/R) * ((1/320) - (1/300))
We can assume that R is constant, so we can solve for Ea:
Ea = (-1.355 * R) / ((1/320) - (1/300))
Ea = 25,620 J/mol
Now we can use this value for Ea to find the rate constant at 47 C:
k2 = k1 * e^[(Ea/R) * ((1/T2) - (1/T1))]
k2 = 0.002 * e^[(25,620 / (8.314 J/mol-K)) * ((1/320) - (1/300))]
k2 = 0.016/hr
Therefore, the rate constant at 47 C is 0.016/hr.

blood test indicates the presence of a particular disease 93% of the time when the disease is actually present. The same test indicates the presence of the disease 0.4% of the time when the disease is not present. Three percent of the population actually has the disease. Calculate the probability that a person has the disease given that the test indicates the presence of the disease. Give your answer in decimal form, rounding to four decimal places.
Answers
The probability that a person has the disease given that the test indicates the presence of the disease is approximately 0.9968
To calculate the probability that a person has the disease given that the test indicates the presence of the disease, we can use Bayes' theorem.
Let's denote:
A = Event of having the disease
B = Event of the test indicating the presence of the disease
We are given the following probabilities:
P(A) = 0.03 (3% of the population actually has the disease)
P(B|A) = 0.93 (the test indicates the presence of the disease 93% of the time when the disease is actually present)
P(B|not A) = 0.004 (the test indicates the presence of the disease 0.4% of the time when the disease is not present)
We need to find P(A|B), the probability that a person has the disease given that the test indicates the presence of the disease.
Applying Bayes' theorem:
\(P(A|B) = (P(B|A) * P(A)) / P(B)\)
To calculate P(B), we can use the law of total probability:
\(P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)\)
\(P(not A) = 1 - P(A) = 1 - 0.03 = 0.97\)
Substituting the values into the equation:
\(P(B) = (0.93 * 0.03) + (0.004 * 0.97) ≈ 0.0279\)
Now, calculating P(A|B):
\(P(A|B) = (0.93 * 0.03) / 0.0279 ≈ 0.9968\)
Therefore, the probability that a person has the disease given that the test indicates the presence of the disease is approximately 0.9968 (rounded to four decimal places).

(D) Hydrofluoric acid is not a strong acid. While it is a highly corrosive and dangerous acid, it is not classified as a strong acid because it does not completely dissociate in water to produce H+ ions.
Hydroiodic acid (HI), on the other hand, is considered a strong acid only in concentrated form. In dilute solutions, it behaves as a weak acid, meaning that it does not dissociate completely in solution, resulting in a lower concentration of H+ ions. Therefore, hydroiodic acid is not considered a strong acid under normal conditions.

will decreasing the tbcl concentration affect the rate constant in this experiment? explain why or why not
Answers
Decreasing the TBCl concentration will not affect the rate constant in this experiment. The rate constant is determined by the specific reaction and temperature conditions and is independent of the reactant concentrations.
The rate constant (k) is a proportionality constant that relates the rate of a reaction to the concentrations of the reactants. However, the rate constant itself is not affected by the concentrations of the reactants. It is determined by the specific reaction and temperature conditions.
The rate of a chemical reaction can be expressed using the rate equation, which typically includes the concentration terms for the reactants raised to certain powers.
These powers, known as reaction orders, can be determined experimentally. However, the rate constant is a separate factor in the rate equation and is not dependent on the reactant concentrations.
By decreasing the TBCl concentration, the rate of the reaction may be affected, as the rate is directly proportional to the reactant concentrations.
However, the rate constant itself remains unchanged. The rate constant is influenced by factors such as temperature, presence of catalysts, and the nature of the reacting species, but not by the concentrations of the reactants.
Therefore, decreasing the TBCl concentration will not affect the rate constant in this experiment.

Noble gases have __ values of ionization energy due to their complete outermost shells
Answers
Answer:
high
Explanation:
The energy needed to ionize a neutral atom is known as ionization energy. An atom must have one or more electrons removed from its valence shell in order to get ionized and become a cation. Alternately, you must produce an anion by adding one or more electrons to the valence shell. The energy needed for ionization will be lower the fewer electrons are supplied or withdrawn. As a result, atoms having an incomplete valence shell have a tendency to ionize more quickly and with less energy. However, entire valence shell atoms will require a large amount of ionization energy. As a result, noble gases need significant energy to ionize since they contain a full valence shell, are extremely stable, and do not tend to ionize easily.

Answers
The empirical formula of the compound with 79.9 mass % carbon is CH₃H₉.
What is empirical formula?
The empirical formula of a compound is the simplest, most reduced ratio of the atoms present in the compound. It represents the relative number of atoms of each element in the compound, without providing information about the actual number of atoms or the molecular structure.
1. Determine the mass of carbon in 100 grams of the compound:
Mass of carbon = 79.9% * 100g = 79.9g
2. Determine the mass of hydrogen in 100 grams of the compound:
Mass of hydrogen = (100% - 79.9%) * 100g = 20.1g
3. Calculate the number of moles of carbon:
Number of moles of carbon = Mass of carbon / atomic mass of carbon
Number of moles of carbon = 79.9g / 12.01 g/mol ≈ 6.659 mol
4. Calculate the number of moles of hydrogen:
Number of moles of hydrogen = Mass of hydrogen / atomic mass of hydrogen
Number of moles of hydrogen = 20.1g / 1.008 g/mol ≈ 19.92 mol
5. Determine the empirical formula by dividing the number of moles by the smallest number of moles obtained:
Ratio of carbon to hydrogen ≈ 6.659 mol / 6.659 mol : 19.92 mol / 6.659 mol ≈ 1 : 2.993
Rounding the ratio to the nearest whole number gives us the empirical formula:
Empirical formula: CH₃
To determine the molar mass of the empirical formula, we need to sum up the atomic masses:
Molar mass ofCH₃ = (112.01) + (31.008) = 15.03 g/mol
Finally, to find the molecular formula with a molar mass of 45.12 g/mol, divide the molar mass of the empirical formula into the desired molar mass:
Molecular formula: (45.12 g/mol) / (15.03 g/mol) = 2.999 ≈ 3
Therefore, the empirical formula would be (CH₃H₃), which is CH₃H₉.

what is the ph of a solution made by mixing 100.0 ml of 0.10 m hno3, 50.0 ml of 0.20 m hcl, and 100.0 ml of water? assume that the volumes are additive.
Answers
The pH of a solution made by mixing 100.0 ml of 0.10 m HNO₃, 50.0 ml of 0.20 m HCl, 100.0 ml of water, and assume that the volumes are additive is 1.10.
To find the pH of the solution made by mixing 100.0 mL of 0.10 M HNO₃, 50.0 mL of 0.20 M HCl, and 100.0 mL of water, we must calculate the moles of HNO₃ and HCl.
Moles of HNO₃ = 100.0 mL × 0.10 M × (1 L / 1000 mL) = 0.01 mol
Moles of HCl = 50.0 mL × 0.20 M × (1 L / 1000 mL) = 0.01 mol
Then, add the moles of HNO₃ and HCl together.
Total moles of H⁺ = 0.01 mol + 0.01 mol = 0.02 mol
Find the total volume of the solution (assume volumes are additive).
Total volume = 100.0 mL + 50.0 mL + 100.0 mL = 250.0 mL
Calculate the concentration of H⁺ ions in the solution.
[H⁺] = (0.02 mol) / (250.0 mL × 1 L / 1000 mL) = 0.08 M
Find the pH using the formula pH = -log10([H+]).
