One mole of non`-` ideal gas undergoes a change of state `(1.0 atm, 3.0L, 200 K )` to `(4.0 atm, 5.0L,250 K)` with a change in internal energy `(DeltaU)=40 L-atm`. The change in enthalpy of the process in `L-atm`,

A

43

B

57

C

42

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
When both P and V are changing
`" "DeltaH=DeltaU +Delta(PV)`
`" "DeltaU+(P_(2)V_(2)-P_(1)V_(1))`
`" "DeltaH=40+(20-3)`
= 57 L-atm
