Teaching CSIR NET Mock Test Series Chemical Sciences Chemical Kinetics Empirical Rate Laws and Temperature Dependence
The correct statement about the activation energy (Ea) in the Arrhenius equation is that:
1
It is independent of temperature.
2
It determines the rate of a reaction without considering the pre-exponential factor.
3
It is the minimum energy required for a reaction to occur.
4
It decreases as the reaction progresses.
