The difference between DeltaH and Delta ...

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

A

`PdeltaV`

B

R

C

`V Delta P`

D

`(3)/(2) R`

Text Solution

Verified by Experts

The correct Answer is:
C

`DeltaH=DeltaE+Delta(PV)`
or `DeltaH-DeltaE=PDeltaV+VDeltaP.`
At constant volume, `DeltaV=0`
`therefore DeltaH-DeltaE=VDeltaP`
