The rate law can be expressed by:

r = k[reactant]n

From the reaction given:

2 NOBr(g) → 2 NO(g) +Br2(g)

The rate law then becomes:

r = k [NOBr]n

k will be the rate constant. n is the order of the reaction. Before solving for k, we must solve for n.

Substitute the values 1.01x102 for r and 0.600 for reactant in the first rate expression:
