Rate equation for the general reaction
Order of a reaction: The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.
When a reactant is made much more concentrated than the other, it is made to have no effect on the rate of that particular reaction. Such type of reaction is considered as pseudo (fake) order reaction.
