Question

For the elementary reaction NO₃ + CO → NO₂ + CO₂ The molecularity of the reaction is ________,and the rate law is

Quizplus · Accepted Answer

The molecularity of the reaction is the sum of the number of molecules or atoms in the reactants in the rate-determining step. In this case, only one molecule of NO₃ and one molecule of CO are involved in the reaction, so the molecularity is 2. The rate law takes the form of k[NO₃][CO] because the reaction is elementary, and there are no intermediates.
