Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as `k=Ae^(E_(a)//RT)` . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied.
The pre-exponetial factor in the Arrhenius equation of a first order reaction has the unit :
a) `mol L^(-1)s^(-1)`
b) `L mol^(1)s^(-1)`
c) `s^(-1)`
d) dimensionless

Options

A. mol `L^(-1)s^(-1)`
B. L `mol^(1)s^(-1)`
C. `s^(-1)`
D. `dimensionaless

Answer

C
