The Reaction 2A + B  D + E

question 80

Short Answer

The reaction 2A + B  D + E has the rate law,rate = a[A]²[B]/(b + c[A])where a,b,and c are constants.The following mechanism has been proposed for this reaction.
A + B I
k₁,k_-1
I + A  D + E
k₂
I is an unstable intermediate present in minute concentrations.Show that this mechanism leads to the observed rate law and evaluate the constants a,b,and c in terms of the rate constants k₁,k_-1,and k₂.
