(25 points) The following equation of state, with a and b being constants, holds for a pure vapor. PV=RTTaPT2bP2 a. (20 points) Find an expression for the change molar enthalpy if this vapor is taken from P1 and T1 to P2 and T2. You may assume you have a constant value for CPlG and you do not have any values for CP. Report your answer in terms of the constants a,b,CPlG, and R as well as Tl,Pl,T2, and P2. b. (5 points) Find an expression for the residual molar volume of this vapor at P3 and T3. Again report your answer in terms of the constants a,b, and R as well as T3 and P3
