Question

# What is rate constant ? Write 'two applications' of rate law.

Solution

## The rate constant of a chemical reaction is defined as the rate of the reacton when concentration of all reactants are unity, i.e., $$1$$ mole / litre, for e.g., for a reaction,$$A\longrightarrow$$ ProductsRate, $$R=k\left[ A \right]$$if $$\left[ A \right] =1mol{ l }^{ -1 }$$, then    $$k=R$$where, $$k$$ = Rate constant or proportionality constant.The rate constant is the rate of the reaction when all the concentrations are set equal to unity.The applications of rate law are :(a) It can be used to estimate the rate of a reaction for any given composition of the reaction mixture.(b) It can be used to predict the mechanism of a complex reaction.ChemistryNCERTStandard XII
