Question

Consider the following mechanism step 1: A+ B, step 2: AB+B, АВ+ В В,+A — overall: 2В, — В, + В Which species is an intermedi

Answer 1

Answer #1

1)

Intermediates are produced in one step and are used up in next steps

AB is produces in step 1 and used up in step 2

So, AB is an intermediate

Answer: AB

2)

Catalyst are used as reactant 1st and later produced as product.

A is reactant in step 1 and product in step 2

SO, A is catalyst

Answer: A
