Select the incorrect statement:

Options

A. Half life period of all reactions decreases with increase in temperature
B. Half life period of I order reaction is always constant
C. Higher is rate constant of a reaction, lesser will be its energy of activation
D. Rate of reaction whether exothermic or endothcrmic usually increases with temperature

Answer

C

Explanation

`k=Ae^(-E//RT)` k depends upon `E_(a)` T and nature of reaction but always increases with T the rate increases with decreases in `E_(a)`
