A plot of ln k against `(1)/(T)` (abscissa) is expected to be a straight line with intercept on coordinate axis equal to

A

`(DeltaS^(@))/(2.303 R)`

B

`(DeltaS^(@))/R`

C

`-(DeltaS^(@))/R`

D

`R xx DeltaS^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaG^(@) = -RT ln K`
or `DeltaH^(@) -T DeltaS = -RT ln K` or `ln K = (-DeltaH^(@))/(RT) + (DeltaS^(@))/R`
Comparing with y= mx +c y intercept is `(DeltaS^(@))/R`
