Question

If Ea = 0, then the rate constant k:
  1. A
    Is independent of temperature
    Correct
  2. B
    Increases with temperature
  3. C
    Decreases with temperature
  4. D
    Becomes zero

Correct answer

Is independent of temperature

Explanation

k = Ae^(−Ea/RT). If Ea = 0: k = Ae^0 = A, a constant independent of T. Such reactions have no temperature dependence.
