If a reaction is 1st order with respect to [A] and 2nd order with respect to [B], doubling the concentration of reactant [B] will result in a four-fold increase in the rate of reaction.

Question

Quizplus · Accepted Answer

Doubling the concentration of [B] in a reaction that is second order with respect to [B] will increase the rate of the reaction by $2^2 = 4$ times, hence a four-fold increase.
