Find the correct equation....

Find the correct equation.

A

`E_(2)-E_(1)-H_(2)+H_(1)=n_(2)RT-n_(1)RT`

B

`E_(2)-E_(1)-H_(2)-H_(1)=n_(2)RT+n_(1)RT`

C

`H_(2)-H_(1)-E_(2)+E_(1)=n_(2)RT-n_(1)RT`

D

`H_(2)-H_(1)-E_(2)+E_(1)=n_(2)RT+n_(1)RT`

Text Solution

Verified by Experts

The correct Answer is:
C
We know that, `DeltaH=DeltaE+Deltan_(g)RT`
`H_(2)-H_(1)=E_(2)-E_(1)+(n_(2)RT-n_(1)RT)`
or `H_(2)-H_(1)-E_(2)-E_(1)=n_(2)RT-n_(1)RT`
