The activation energy of a reaction can ...

The activation energy of a reaction can be determined from the slope of which of the following graphs ?

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
According to Arrhenius equation,
`k = Ae^(-E_(a)//RT)`
`ln k = ln A - (E_(a))/(RT)`
Hence, if ln k is plotted against `1//T`, slope of the line will be `-E_(a)//Rt`
