If the units for rate are M s^-1,what are the units for the rate constant,k,if the overall order of the reaction is five?

Question

Quizplus · Accepted Answer

The units of the rate constant, k, depend on the overall order of the reaction. For a reaction of overall order 5, the units of k can be derived from the rate equation, rate = k[A]^m[B]^n..., where m+n+...=5. Given the units of rate (M s^-1), and knowing the reaction order is 5, the units for k must offset the concentration units raised to the power of 4 (since one concentration term is already present in the rate's units), resulting in M^-4 s^-1 for k's units.
