Which of the following statements is true?
A rigid vessel with known volume initially contains 10 moles of A and 10 moles of B at 298.15 K, and nothing else. The reaction A+B?C+D occurs in the liquid phase, but not in the vapor phase. When the vessel reaches equilibrium, at 298.15 K, both a liquid and a vapor phase are present. The equilibrium constant for the reaction is 0.4. 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. You are trying to calculate the eight unknown values of number of moles (N), one for each compound in each phase that will be present at equilibrium.
