Question 3 of 96

One mole of a non-ideal gas undergoes a change of state (2.0 atm, 3.0 L, 95 K)(4.0 atm, 5.0 L, 245 K) with a change in internal energy, U = 30.0 L atm. The change in enthalpy (H) of the process in L atm is:

(a) 40.0

(b) 42.3

(c) 44.0

(d) not defined, because pressure is not constant
