FREE Expert Solution

We are being asked to determine the intermediate and catalyst in the following mechanism


step 1: A + BC  ABC

step 2: BC + ABC  A + B2 + C2

overall: 2 BC  B2 + C2


Recall

the intermediate is the specie that is formed by the reactants but is used up to further form the products

the catalyst is the specie that speeds up the reaction and is not used up.
