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
Get the overall reaction:
Cancel the intermediate species.
The proposed mechanism for a reaction is
NO + O3 => NO3 + O Fast
NO3 + O => NO2 + O2 Slow
Which of the following would be a rate law for the reaction?
