Determine the enthalpy change (h) and the entropy change (s) of nitrogen per unit mole as it

Determine the enthalpy change (Δh) and the entropy change (Δs) of nitrogen per unit mole as it undergoes a change of state from 225 K and 6 MPa to 320 K and 12 MPa,
(a) By assuming ideal-gas behavior
(b) By accounting for the deviation from ideal-gas behavior through the use of generalized charts (L-K model).
