Hydrogen sulfide gas is compressed from an initial state of 400 K and 2 bars to a final state of 598 K and 36 bars. Estimate the ΔH using generalized correlations. You may assume that hydrogen sulfide behaves as an ideal gas at the initial conditions with a constant average heat capacity of CP = 19 kJ/mol K.
