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

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