Problem: The reaction 2NO2 → 2NO + O2 has the rate constant k = 0.63 M-1s-1.Based on the units for k, is the reaction first or second order in NO2?

FREE Expert Solution

We’re being asked to determine the order of the reaction given the rate constant, k = 0.63 M-1s-1, for the given reaction:

 2 NO2 → 2 NO + O2


Recall that in order to determine the unit of k, the following equation is used:

k=M-n+1·t-1

n = overall order of the reaction

t = seconds, s
