Question

Study the steps in the reaction mechanism.

elementary step 1: Cl+O3⟶ClO+O2

elementary step 2: ClO+O⟶Cl+O2

 Give the overall reaction that this mechanism describes.

overall reaction:

Answer 1

An intermediate is not present at the beginning. It forms during the reaction and disappears before the end. It does not appear in the final equation.

Overall reaction ;

$O_3+ O → 2O_2$
