Consider the reaction A + B → C. Doubling the concentration of A leads to doubling the rate, while doubling the concentration of B quadruples the rate. The rate equation is, therefore, ________.

Question

Quizplus · Accepted Answer

The rate equation is determined by the order of the reaction with respect to each reactant. Since doubling [A] doubles the rate, the reaction is first order with respect to A. Since doubling [B] quadruples the rate, the reaction is second order with respect to B. Therefore, the rate equation is Rate = k[A][B]^2.
