For a reaction with a second order rate constant, what is the correct unit?

Question

Quizplus · Accepted Answer

For a second order reaction, the rate constant k has units of M-1 ∙ time-1. This is because the rate of reaction is proportional to the concentration of both reactants raised to the power of 1, hence the term M-1. The term time-1 comes from the fact that the rate is dependent on the time it takes for the reactants to react. Therefore, the correct unit for k is M-1 ∙ time-1.
