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^(@))/(2.303R)`

B

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

C

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

D

`RxxDeltaS^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaG^(@)=-RT` ln K
or , `DeltaH^(@)-TDeltaS^(@)=-RT" lnK or, lnK"=(-DeltaH^(@))/(RT)+(DeltaS^(@))/(R)`
Comparing with y=`m*x+c`
Intercept is `(DeltaS^(@))/(R)`
