SOLVED: Texts: QUESTION 4A. Explain why ideal gas heat capacities are used for calculation of property changes for real gases under the departure function methodology. [4 marks]B. The computed departure function of a property is a positive numerical value. (Yes or No? Why?) [4 marks]C. The enthalpy departure in terms of volume-explicit (v = v(T,P)) volumetric Equation Of State (EOS) is given by Equation (4C) below:hp = 5p - 0[-T]aP Eq. (4C i)i) compressibility factor Z and pressure-explicit (P =
