Problem

Consider this overall reaction, which is experimentally observed to be second order in X and first order in Y: X + Y → XY

Is this two-step mechanism valid?
There are 2 schemes of reactions. The first reaction labeled fast is a reversible one and has 2X forming X2. The constant of the forward reaction is k1, and the constant of the reversed reaction is k2. The second reaction labeled slow is irreversible. Here X2 reacts with Y in order to form XY and X. The constant of this reaction is k3.
