Compute the standardized enthalpy and entropy of a mixture formed by an equal mass amount of CO_2?and H₂O at 2 atm and 311 K. If liquid is present for these conditions, assume that the vapor phase can be approximated as an ideal gas mixture, and the liquid phase is pure water. Use:?

a) Values obtained from Table A.1, and?

b) values obtained with GASMIX. If there is a difference, explain it.
