Concentration of Product B in Set of Two Parallel Reactions Formula

What are Parallel Reactions?

Parallel reactions are also called concurrent reactions. In these reactions the reacting molecules react or decomposes in more than one ways yielding different sets of products.
The reaction yielding maximum amount of product is known as the main or major reaction and the other reactions are referred to as side or parallel reactions.

What is Set of Two Parallel Reactions?

In a set of two parallel reactions two first order reactions takes place concurrently. Starting from a reactant (here, A) two elementary reactions take place parallelly to give products ( here, B and C ), having reaction rate constants k1 and k2 respectively.
A→B , here rate constant = k1
At the same time,
A →C , here the rate constant = k2
