Assertion : If the activation energy of a reaction is zero, temperatur

1.	Assertion : If the activation energy of a reaction is zero, temperature will have no effect on the rate constant. Reason : Lower the activation energy, faster is the react ion (a) If both assertion and reason are true and the reason is the correct explanation of the assertion. (b) If both assertion and reason are true and the reason is not the correct explanation of the assertion. (c) If assertion is true but reason is false (d) If assertion is false but reason is true
Answer» Correct Option (b) If both assertion and reason are true and the reason is not the correct explanation of the assertion. Explanation : According to Arrhenius equation, K = Ae^{-Ea /RT} when EA = 0, K = A.
