The difference between DeltaH and Delta ...

The difference between `DeltaH` and `Delta E` at constant voluem is equal to

A

`R`

B

`pDeltaV`

C

`Vdeltap`

D

`(3)/(2)R`.

Text Solution

Verified by Experts

The correct Answer is:
C
`H=E+PV`
Taking `Delta` on both the sides
`DeltaH=DeltaE+Delta(PV)=DeltaE+PDeltaV+VDeltaP`
At constant volume, `DeltaV=0`
`:. DeltaH=DeltaE+VDeltaP`
or `DeltaH-DeltaE=VDeltaP`
