FREE Expert Solution

We're being asked if the mechanism valid for the reaction:

AB + C → A + BC


Recall that the rate law can be determined using the slow step in the reaction mechanism.

 rate law only involves the reactants
▪ the coefficients of the reactants in the slow step are the order of the reaction with respect to that reactant
▪ Rate Law has a general form of:

Problem Details

Consider this overall reaction, which is experimentally observed to be second order in AB and zero order in C

AB + C → A + BC

Is the following mechanism valid for this reaction?

The figure shows 2 schemes of reaction. In the first reaction labeled slow, AB reacts with AB and gets AB2 and A. The constant of the reaction is k1. In the second reaction labeled fast, AB2 reacts with C in order to form AB and BC. The constant of the reaction is k2.
