One mole of a non-ideal gas undergoes a change of state `(2.0atm,3.0L,95K)rarr(4.0atm,5.0L,245K)`
With a change in internal energy `DeltaE=30L` atm. The change in enthalpy `(DeltaH)` in the process in `L`-atm is

A

`40.0`

B

`42.3`

C

`44.0`

D

Not defined, because pressure is not cosntant

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaH=DeltaE+Delta(PV)=DeltaE+(P_(2)V_(2)-P_(1)V_(1))`
or `DeltaH=30+(20-6)=30+14=44L`-atm.
