Question

How is specific reaction rate different from the reaction rate?

In what respect does specific reaction rate differ from the rate of reaction?

Answer 1

Sr. No.	Reaction rate (rate of reaction)	Specific reaction rate (rate constant)
1.	It is the rate at which a reactant or product concentration changes in relation to time.	When the molar concentration of each reactant is unity, it is a proportionality constant that equals the rate of reaction.
2.	The concentration of reactants at a given moment determines the reaction rate at that moment.	For a given reaction at a given temperature, the specific reaction rate stays constant and is independent of reactant concentration.
3.	Its units are fixed and are mol L−1 s−1.	Its units depend upon the order of reaction. For a reaction of order n, the units of specific reaction rate are mol1 − n Ln − 1 s−1.
