One "mole" of a nonideal gas undergoes a change of state (2.0 atm, 3.0 L, 95 K) to (4 atm, 5L, 245 K) with a change in internal energy, Deltau=30.0L atm. The change in enthalpy, DeltaH, of the process in L. atm is

Answer»

<P>`40.0`
`42.3`
`44.0`
not DEFINED , because pressure is not constant

SOLUTION :`DeltaH=Deltau+(p_(2)V_(2)-p_(1)V_(1))`
