Solve the following using ThermoSolver:

(a) In Species Database, select Ethane. Report its critical temperature and pressure and Δhf,298 o .

(b) In Saturation Pressure Calculator, fi nd the saturation temperature of ethane at 40 bar.

(c) In Equation of State Solver, fi nd the volume and compressibility factor of ethane in the following states using the Lee–Kesler equation (generalized correlations) and the Peng– Robinson equation. Report the value of each and the percent difference between the two methods:

(i) P = 40 bar, T = 290 K; 

(ii) P = 40 bar; T = 302 K.
