The number of given statement/s which is/are correct is_____ (A) The stronger the temperature dependence of the rate constant, the higher is the activation energy. (B) If a reaction has zero activation energy, its rate is independent of temperature. (C) The stronger the temperature dependence of the rate constant, the smaller is the activation energy. (D) If there is no correlation between the temperature and the rat

Correct answer

0

Step-by-step solution

Rate constant is given by Arrhenius equation k = Ae - E a / R T Higher the magnitude of activation energy, stronger is the temperature dependence of the rate constant. The pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy. If the activation energy of reaction is zero, temperature will have no effect on the rate constant.
