A hypothetical reaction, X 2 ​ + Y 2 ​ ⟶ 2 X Y follows the following mechanism X 2 ​ ⇌ X + X … ...... . fast X + Y 2 ​ ⟶ X Y + Y …… slow X + Y ⟶ X Y .......... fast The order of the overall reaction is

TestHub · Accepted Answer

Rate = k [ X ] [ Y 2 ​ ] But, k = [ X 2 ​ ] [ X ] 2 ​ or, [ X ] = k ⋅ [ X 2 ​ ] ​ Rate = k ⋅ k ​ [ X 2 ​ ] ​ [ Y 2 ​ ] = k ′ [ X 2 ​ ] 1/2 [ Y 2 ​ ] Thus, order, = 1 + 2 1 ​ = 2 3 ​
