When the concentration of A is doubled,the rate for the reaction: 2 A + B → 2 C quadruples. When the concentration of B is doubled the rate remains the same.Which mechanism below is consistent with the experimental observations?

The rate-determining step is the slow step, which involves only A, consistent with the rate quadrupling when A is doubled. B does not appear in the slow step, so doubling B does not affect the rate.

When the Concentration of a Is Doubled,the Rate for the Reaction
