The rate constant for a certain reaction has the units concentration time^-1. What is the order of the reaction?

Question

^{The rate constant for a certain reaction has the units concentration time^-1. What is the order of the reaction?}

Answer 1

A zero order reaction has the equation ΔConc./ Δtime = K. In this case the rate constant K has the units conc. time^-1.

Answer 2

Different order reactions have different units for their rate constant, k. If the units are concentration time^-1, such as Ms-1 (M/sec), this is zero order. Others are...

First order k = time^-1

Second order k = concentration^-1 time^-1
