Question

Calculate the enthalpy and entropy of the saturated vapor of isobutane at 360 K from the following information:

1. Table 6.1 provides the compression factor information (Z values) for isobutane vapor.

2. The vapor pressure of isobutane at 360 K is 15.41 bar.

3. Consider H0g = 18 115.0 J mol ^ -1 and S0g = 295.976 J mol ^ -1* K ^ -1 for the reference state of an ideal gas at 300 K and 1 bar.

4. The heat capacity of the ideal gas of the isobutane vapor at the temperatures of interest:

Cp / R = 1.7765 + 33.037x10 ^ -3T (T / K)

Use the Table 6.1: Z compressibility factors for isobutane. (text book "Introduction Termodymanic in chemical engineering edition 7")
