# Problem: The proposed mechanism for a reaction isNO + O3 =&gt; NO3 + O      FastNO3 + O =&gt; NO2 + O2   SlowWhich of the following would be a rate law for the reaction?

###### FREE Expert Solution

We are being asked to write a rate law for the reaction using the provided mechanism.

Rate law is a mathematical equation that links the rate of a chemical reaction with the concentrations of its reactants.

Rate law is written using the slow step of the reaction (also called the rate-determining step)

Recall that the rate law only focuses on the reactant concentrations and has a general form of:

k = rate constant
A & B = reactants
x & y = reactant orders
