Problem Details

Which of the following is a plausible reaction mechanism for 2 H 2 + O2 → 2 H2O, given that the reaction was found to have a rate law of Rate = k [H2] 2?

A.) 2 H2 + O2 → 2H2O slow

B.) H2 + O2 → 2 OH slow

OH + H2 → H2O + H

OH + H → H2O

C.) H2 + H2 → 4 H slow

 2 H + O2 → 2 OH

H + OH → H2O

H + OH → H2O

D.) H2 + H2 → 4 H slow

4 H + O2 → 2 H2O
