Question

What do you understand by rate law of a reaction?

What is rate law?

What is meant by the rate law?

Answer 1

1. The mathematical expression that describes the experimentally observed dependence of the reaction rate on the molar concentrations of the reactants is called the rate law or rate equation.
2. The actual relationship between the rate of reaction and the reactant molar concentrations is described by the rate law.
3. Each concentration word raised to the power indicating the actual dependency of the rate on the concentration is used in the rate law to express the rate of reaction as the product of the molar concentrations of reactants.
4. In the balanced chemical equation, this power might or might not be equivalent to the reactant’s stoichiometric coefficient.
