The proposed mechanism for a reaction is:
Step 1: A+B= X(fast)
Step 2: X+C - Y(slow)
Step 3: Y - D (fast)
Which rate law is consistent with this mechanism?
-
O A.
rate = k[A][B]
ОВ.
rate = K[X][C]
O C.
rate = k[A][B][C]
OD.
rate = k[X][Y]
=

When you are solving for rate law, you are only looking at the reactants of the slow reaction. In this case, step 2 is the slow one. Since there is only one X and one C on the reactants side, the coefficient in the rate law would each be one, which you don't need to include, as it is assumed.
