Which statement below regarding the half-life of a second-order reaction is true?

Question

Quizplus · Accepted Answer

In a second-order reaction, each half-life is twice as long as the preceding one. This is because the rate constant for a second-order reaction is directly proportional to the concentration of both reactants, and as the reactants are consumed during the course of the reaction, the concentrations decrease and thus the rate constant also decreases. As a result, the time required for half of the initial concentration to react (i.e. the half-life) increases with each subsequent half-life.
