WEBUnits. The units of the rate constant depend on the overall order of reaction. If concentration is measured in units of mol·L −1 (sometimes abbreviated as M), then For order (m + n), the rate constant has units of mol 1−(m+n) ·L (m+n)−1 ·s −1 (or M 1−(m+n) ·s −1) For order zero, the rate constant has units of mol·L −1 ·s − ...
