Difference between rate of reaction and reaction rate constant .

Answered by admin @ 26/08/2021

As temperature varies, so does thereaction rate constant. ... 1.Reaction rate or rate of reaction is the measure of how fast or slow a chemicalreaction occurs in the conversion of a reactant into a product while a reaction rate constant gives a comparative amount of the reaction rates of reactants and products.
