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 Ea RT . A a

Options

  1. AA, C and D Only
  2. BB , D and E Only
  3. CB and C Only
  4. DA and B Only

Correct answer

C. B and C Only

Step-by-step 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.
