WebWhen you say instantaneous reaction, it means very fast reaction. The rate of change of concentration of reactants per unit time is very high and hence the rate of reaction is very fast. The concentration of the reactants have a finite value whereas for the value of rate of reaction to be high, the value of rate constant has to be very high. WebThe reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
