Under which of the following conditions ...

Under which of the following conditions is the relation, `Delta H = Delta E + P Delta V` valid for a system :-

A

constant pressure

B

constant temperature

C

constant temperature and pressure

D

constant temperature, pressure and composition

Text Solution

Verified by Experts

The correct Answer is:
A
`H=E+PV :. DeltaH = DeltaE + P DeltaV + V DeltaP `. If P is constant, i.e., `DeltaP =0`,only then `DeltaH = DeltaE + P DeltaV`
