RATE OF CHEMICAL REACTIONS
It may be defined as the number of moles of the solute present in one liter of solution. So,
If 1 mol of the solute is present in 1 L of the solution, we say that the solution is one molar or concentration of the solution is 1 M i.e. molarity of solution is 1.
Representation of Molarity
In chemical reactions the Molarity of a reactant or a product is represented by putting its symbol or formula within a square bracket, [ ]. For example, in reaction
The molar concentration of reactants nitrogen and hydrogen can be represented as [H2] and [N2] respectively while molar concentration of product ammonia can be represented as [NH3]
