What is multi step reaction?

A multi-step reaction is a combination of two or more elementary steps. An elementary step is a single, simple step involving one or two particles. The rate-determining step is the slowest step in a multi-step reaction, and the overall reaction rate will be exactly the same as the rate of the slowest step.

What is parallel reaction?

The reactions in which one or more reactants react simultaneously in two or more pathways to give two or more products are known as parallel (or) side reactions.
