Identify the correct statements,
A. The Arrhenius equation holds true only for an elementary homogenous reaction.
B. The unit of A is same as that of k in Arrhenius equation.
C. At a given temperature, a low activation energy means a fast reaction.
D. A and Ea as used in Arrhenius equation depend on temperature.
E. When $Ea ≫ RT$ . A and Ea become interdependent.
Choose the correct answer from the options given below :

Options:

Answer:

C

Solution:

Arrhenious equation hold true for elementary as well as complex reactions.
Unit of A is same as unit of k. Rate of reaction is high if activation energy is low,
A and Ea are temperature independent.
