Question

In the respect of the equation k = Ae–Ea/RT in chemical kinetics, which one of the following statements is correct :

• A. K is equilibrium constant
• B. A is adsorption factor
• C. Ea is energy of activation
• D. R is Rydberg constant.

Answer 1

Answer: (C)

Ea is energy of activation

Answer 2

n Arrhenius equation, $\text{k = A}\text{e}^{\text{ -Ea/RT}}$

k = rate constant, A = frequency factor

T = temperature, R = gas constant, Ea = energy of activation.

This equation can be used for calculation of energy of

activation.
