The variation of rate constant with temp...

The variation of rate constant with temperature can be explained by Arrhenius equation. However , the can be explained by Activation energy is found to be temperature dependent/In such cases`(d"in"K)/(dT)=(E_(a))/(RT^(2))` should be used to predict variation of rate constant with tempreature. On the basic of this information , answer the question that follow :
Which if the following statement is not correct ?

A

Temperature coefficient of a reaction at high temperature will be less

B

Reaction with no activation energy will have no change in rate constant due to temperature

C

The factor by which catalyst increase rate constant will be same at all the temperature

D

Greater the activation energy, more sanitive will the rate constant be cecause of temperature
