(C) The enthalpy change is given by the formula: $\Delta H = \Delta U + \Delta (PV)$ Substituting $\Delta (PV) = P_2 V_2 - P_1 V_1$: $\Delta H = \Delta U + (P_2 V_2 - P_1 V_1)$ Given $\Delta U = 30.0 \, 	ext{L} \cdot 	ext{atm}$,$P_1 = 2.0 \, 	ext{atm}$,$V_1 = 3.0 \, 	ext{L}$,$P_2 = 4.0 \, 	ext{atm}$,and $V_2 = 5.0 \, 	ext{L}$: $\Delta H = 30.0 + (4.0 	imes 5.0 - 2.0 	imes 3.0)$ $\Delta H = 30.0 + (20.0 - 6.0) = 30.0 + 14.0 = 44.0 \, 	ext{L} \cdot 	ext{atm}$.
