Which of the following is NOT true?
A reaction A+B?C occurs in the liquid phase. A vessel contains a liquid at P = 1 MPa and T = 298.15 K. The vessel initially contains 10 moles of A and 10 moles of B, but the reaction is allowed to reach equilibrium at P = 1 MPa and T = 298.15 K. After the reaction reaches equilibrium, the pressure is reduced isothermally until it reaches 0.13 MPa, at which point the first bubble of vapor forms. The liquid at this point is 39 mol% A, 39 mol% B and 22 mol% C. The first bubble of vapor is 52 mol% A, 40 mol% B and 8 mol% C.
