Question

Consider the following overall reaction which is experimentally observed to be second order in AB and zero order in C: 
AB+C -> A+BC

Determine whether the mechanism below is valid for this reaction 
AB+ AB -> AB(sub 2) + A slow 
AB(sub2) + C -> AB+BC fast

jv · Answer

For this question you must fallow the 2 main rules of mechanisms. 1)The slowest elementary (RDS)step must match the rate law of the given rate law. 2)The mechanisms must match the given reaction after crossing out the intermediates of the reactions in the mechanisms.
