Appropriate units for a first-order rate constant are A) M/s. B) 1/M·s. C) 1/s. D) 1/M²·s.

Question

Quizplus · Accepted Answer

The appropriate units for a first-order rate constant are 1/s which are called as rate constants or specific rate constants. The rate of a reaction depends only on the concentration of the reacting species raised to the power of its order in the rate law equation. As the power of each species is a constant value, a first-order reaction’s specific rate constant has units of 1/s.
