Practice Questions
Question 1
Which of the following best describes the units of a rate constant for a first-order reaction?
Question 2
Which of the following correctly describes how the rate of reaction changes over time for a typical reaction without a catalyst?
Question 3
If the rate of a reaction is directly proportional to the square of the concentration of one reactant, which of the following best describes the order of the reaction with respect to that reactant?
Question 4
A reaction has a rate law given by $\text{rate} = k[A][B]^2$. If the concentration of $[B]$ is halved and $[A]$ remains constant, by what factor will the rate change?
Question 5
Which of the following factors typically increases the frequency of effective collisions between reactant molecules, thereby increasing the rate of reaction?
