Explanation

Order And Molecularity

Molecularity of Reaction

A chemical reaction that occurs in a single step is called a single chemical reaction while a chemical reaction happening in the sequence of at least two steps is called a complicated chemical reaction. The sequence of steps through which a convoluted reaction takes place is called the reaction – mechanism. Each step in a mechanism is a basic step reaction.

The molecularity of a basic reaction is characterized as the minimum number of atoms, molecules,  or ions of the reactants(s) that are needed for the reaction to happen and is equivalent to the algebraic sum of the stoichiometric coefficients of the reactant(s) in the chemical equation.
