What is the Order of Reaction?

For any elementary or complex reaction, the order of a reaction is defined as,

“Sum of the coefficients of the reacting compounds that are involved in the rate equation for the reaction.”

The order of Reaction is an experimental value i.e. it is always calculated experimentally.

Order and Molecularity of Reaction

The order of a reaction and the Molecularity of the reaction is the basic properties of the reaction that helps to get the kinematics and rate of reaction. In this article, we will learn about the Order of Reaction and Molecularity, its types differences, and others in detail.
