The activation energy of a reaction can ...

The activation energy of a reaction can be determined from the slop of which of the following graph ?

A

ln k vs `(1)/(T)`

B

`(T)/("ln k")"vs"(1)/(T)`

C

ln k vs T

D

`("ln k")/(T)"vs"T`

Text Solution

Verified by Experts

The correct Answer is:
A
From Arrhenius eqution,
`Ae^(-E_a//RT)" "or" in k = in A - E_a/(RT)`
Thus, plot of In k vs `1/T` will be linear with slope
`=-E_a/R`
