Question

(D) The Arrhenius equation is given by $k = A e^{-E_a / RT}$.As $T 	o \infty$,the term $E_a / RT 	o 0$.Therefore,$k = A e^0 = A 	imes 1 = A$.Thus,t

Vedclass · Accepted Answer

The rate constant of a reaction becomes equal to the pre-exponential factor when the absolute temperature is infinity.

(D) The Arrhenius equation is given by $k = A e^{-E_a / RT}$.As $T 	o \infty$,the term $E_a / RT 	o 0$.Therefore,$k = A e^0 = A 	imes 1 = A$.Thus,the rate constant $k$ becomes equal to the pre-exponential factor $A$ at infinite temperature.Molecularity is always a whole number (integer) and cannot be fractional or zero.Zero order reactions do stop when the reactant is completely consumed.First order reactions can be either homogeneous or heterogeneous.
