Question

Differentiate between rate of reaction and rate constant of a reaction.

How does rate constant differ from the reaction rate?

Answer 1

Sr. No.	Rate of reaction	Rate constant of a reaction
1.	It is the rate at which a reactant or product concentration changes in relation to time.	It is a proportionality constant that equals the reaction's outcome when each reactant's molar concentration is unity.
2.	The concentration of reactants at a given time determines the reaction rate at that time.	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.
