G What is the rate law for the elementary step OH+H2→H+H2OOH+H2→H+H2O? What is the rate law for the elementary step ? Rate=k[H2]Rate=k[H2] Rate=k[OH]Rate=k[OH] Rate=k[H2O][H]Rate=k[H2O][H] Rate=k[OH][H2]

Rate = k [OH][H2]

Explanation:

Reaction mechanism gives the elementary steps for the production of products by the reactants.

Obtain the overall reaction by combining the first step and the second together;

OH + H2 > H  + H2OOH +H2

H + H2OOH + H2 > H + H20

The overall reaction is therefore;

OH + H2 > H + H20

The rate for the elementary step of the reaction is therefore

Rate = k[OH][H2]

fe 55.85 g/mol and h2o 18.02 g/mol.
