For the reaction 2A + B ⟶ D + E the following mechanism has been proposed : A + B ⟶ C + D (slow) A + C ⟶ E (fast) The rate law expression for the reaction is
A.Rate = k [A]2 [B]
B.Rate = k [A] [B]✓ Correct
C.Rate = k [A] [C]
D.Rate = k [A]2 [B] [C]
Explanation
In a complex reaction, slowest step is rate determining step, thus A B C D -> is Rate determining step Thus, 1 1 Rate A B Rate = k A B
