Which of the following expresisons give the effect of temperature on the rate constant?

A

`In A=RT In E_(a)-In K`

B

`ln k = ln A - E_(a)//RT`

C

`k = AE_(a)//RT`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
It is given by Arrhenius equation
`k = Ae^(-E_(a)//RT)`
or `ln k = A-E_(a)//RT`
