Test your understanding of rate laws with 5 practice questions.

Practice Questions

Question 1

Which of the following experimental setups would be most appropriate for determining the rate law of a reaction by measuring the initial rate?

Question 2

For a reaction with the rate law $\text{Rate} = \text{k}[\text{A}]^x[\text{B}]^y$, if the reaction is second order overall and first order with respect to A, what is the order with respect to B?

Question 3

Consider a reaction where the rate law is $\text{Rate} = \text{k}[\text{A}]^2$. If the initial rate of the reaction is $2.0 \times 10^{-4} \text{ M/s}$ when $[\text{A}] = 0.020 \text{ M}$, what is the value of the rate constant $\text{k}$?

Question 4

If a reaction is third order overall, and its rate law is $\text{Rate} = \text{k}[\text{A}]^2[\text{B}]^x$, what is the order with respect to reactant B?

Question 5

Which of the following statements accurately describes the relationship between the rate-determining step and the overall rate law of a reaction?
