Practice Questions

Question 1

Which of the following best describes the relationship between the rate constant $k$ and temperature according to the Arrhenius equation?

Question 2

A reaction has the rate law $\text{rate} = k [A]^2 [B]^0$. If the initial concentration of $A$ is 0.5 M and the rate constant $k$ is 0.4 M^{-1} s^{-1}, what is the initial rate of the reaction?

Question 3

For a reaction with the rate law $\text{rate} = k [A]^1$, which of the following correctly represents the integrated rate law in terms of $[A]$ and time $t$?

Question 4

A reaction has the rate law $\text{rate} = k [A]^1 [B]^2$. If the concentration of $A$ is doubled and the concentration of $B$ remains the same, by what factor does the reaction rate change?

Question 5
