consider the overall reaction: AB(g) + CB(g) ⟶ A(g) + CB2(g)

A proposed mechanism for this reaction is

2 AB(g) ⇌ AB2(g) + A(g) (fast)

AB2(g) + CB(g) ⟶ AB(g) + CB2(g) (slow)

Based on this mechanism, determine the rate law for the overall reaction. Express your answer in terms of k and the necessary concentrations (ex: k[X][Y]^2). Use brackets around the concentrations and the caret symbol prior to the exponent. Do not include any multiplication signs. Type in subscripts as normal numbers (ex: AB2, CB2).
