Rate law

B

Rate equation

C

Differential rate equation

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Rate law is the expression in which reaction rate is given in terms of molar concentration of reactants with each term raised to some power, which may or may not be same as the stoichiometric coefficient of the reacting species in a balanced chemical equation.
