What is the overall order of the following reaction, given the rate law?
NO(g) + O3(g) → NO2(g) + O2(g)
Rate = k[NO][O3]
The overall order of a reaction is determined by adding up the exponents of the concentration terms in the rate law.
In this case, the rate law is:
Rate = k[NO][O3]
The exponent of [NO] is 1, and the exponent of [O3] is also 1.
Therefore, the overall order of the reaction is 1 + 1 = 2.
