Problem

Ozone decomposes catalytically in the presence of chlorine atoms, and the observed rate law is rate=k[O3][Cl]rate = k[O_3][Cl]. A proposed mechanism is: Step 1 (fast): Cl+O3→ClO+O2Cl + O_3 \to ClO + O_2 Step 2 (slow): ClO+O3→Cl+2 O2ClO + O_3 \to Cl + 2\,O_2 Provide one concise reason why this mechanism cannot account for the observed rate law.
