Question

a. Consider the following multistep reaction: m A + B; ightarrow AB;(slow) underline{ m A + AB ightarrow A_2B ; (fast)} ;; m 2A + B ; ightarrow ; A_2B; (overall) Based on this mechanism, determine the rate law for the overall reaction. Express your answer in standard MasteringChemistry format. For example, if the rate law is k[{ m A}]^3[{ m B}]^2 type k*[A]^3*[B]^2. b. Consider the following multistep reaction: ; m C + D ; ightleftharpoons CD;(fast) ; m CD + D; ightarrow CD_2;(slow) {underline { m CD_2 + D ightarrow CD_3;(fast)}} quad m C + ;3D ; ightarrow CD_3;(overall) Based on this mechanism, determine the rate law for the overall reaction. Express your answer in standard MasteringChemistry format. For example, if the rate law is k[{ m C}]^3[{ m D}]^2 type k*[C]^3*[D]^2.

Explanation / Answer

rate of the first one is k[a][b] 2nd one is k[cd][d] but since you cant have an intermediary u have to reset the cd by kf[cd]=kr[c][d] so [cd]=kr/kf [c][d] now plug in and you get k kr/kf [c][d][d] lump the k's into a new k and the final rate expression is k[c][d]^2
