Which of the following statements is true?
A rigid, adiabatic vessel is initially evacuated. 10 moles of liquid A and 10 moles of liquid B at 298.15 K are injected into the vessel, and this 20 moles of liquid is regarded as the “initial state” of the system. When the vessel reaches equilibrium, both a liquid and a vapor phase are present, and the entire equilibrium VLE mixture inside the vessel is regarded as the “final state” of the system. The reaction A+B?C+D occurs in the liquid phase, but not in the vapor phase. The equilibrium constant for the reaction is 0.4 and the reaction is exothermic. The vapor pressures are 0.12 MPa for compound A, 80kPa for compound B, 0.15 MPa for compound C and 70kPa for compound D. The vapor phase can be modeled as an ideal gas, but the liquid phase can NOT be modeled as an ideal solution.
