Question

[Four-digit Integer] One mole of a non-ideal gas undergoes a change of state from (2.0 atm, 3.0 L, 95 K) to (4.0 atm, 5.0 L, 245 K) with ΔU = 30.0 L-atm. The change in enthalpy (ΔH) of the process in L-atm is

Prashant Kotian · Accepted Answer

Correct answer: 0044. ΔH = ΔU + Δ(PV) = 30.0 + (4.0 × 5.0 - 2.0 × 3.0) = 30 + (20 - 6) = 44 L-atm.
