The following reaction mechanism has been proposed for a reaction:
(slow) NO2 + NO2-> NO3 + NO
(fast) NO3 + CO -> CO2 + NO2

  1. Sum the two equations. NO2 cancels on each side, NO3 cancels on each side to leave
    NO2 + CO ==> CO2 + NO

    B. The rate law for the reaction is determined by the slow step; therefore,
    rate = k(NO2)2
