Question

Consider the following statements related to temperature dependence of rate constants.
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 and Ea become interdependent.
Choose the correct answer from the options given below:

Select the correct option:

B and C Only

B, D and E Only

A and B Only

A, C and D Only

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

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.
