The activation energy of a reaction is zero. The rate constant of the reaction:

Options

  1. Aincreases with an increase of temperature
  2. Bdecreases with an increase of temperature
  3. Cdecreases with decrease of temperature
  4. Dis independent of temperature

Correct answer

D. is independent of temperature

Step-by-step solution

From Arrhenius equation, k= A- E_a 2.303 R T As the activation energy of a reaction is zero, the rate constant of this reaction becomes zero. It shows that the reaction is independent of temperature.
