The difference between DeltaH and Delta ...

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

A

`V Delta P`

B

R

C

P Delta V

D

(3)/(2)R

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaH=DeltaE+Delta(PV)`or
`DeltaH=DeltaE+P DeltaV +V DeltaP`
At constant volume `Delta V=0`
`:. Delta H -Delta E =V Delta P`
