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 rate constant then it means that the reaction has negative activation energy.

a, b are correct statement

Higher the activation energy higher is the required temperature for reaction to occur, and hence greater is the temperature dependency of the rate constant.

When the activation energy is zero, the term e ^−Ea/RT becomes equal to 1. Hence, the rate constant becomes independent of the temperature.
