Which of the following statements is definitely accurate?

Question

The reaction A + B ? C occurs in the vapor phase. It is an endothermic reaction. It is beneficial to carry out the reaction in the presence of liquid water, because C is somewhat soluble in water while A and B are effectively insoluble. The Henry’s Law constant for C in water increases as the temperature increases. We are interested in maximizing the total number of moles of C in the system, regardless of whether the C is in the liquid or vapor phase.
A system initially contains 10 moles each of A and B (vapor) and 100 moles of liquid water. The system is allowed to reach equilibrium at T= 298.15 K and 0.1 MPa. In a separate experiment, the system initially contains 10 moles each of A and B (vapor) and 100 moles of liquid water, and is allowed to reach equilibrium at T= 423.15 K and 0.1 MPa.

Answer 1

A. The system at 298.15 K will have more total moles of C.
B. The system at 423.15 K will have more total moles of C.
C. The system at 298.15 K will have a higher mole fraction of C in the vapor phase and a lower mole fraction of C in the liquid phase than the one at 423.15 K. But it is unclear which will have a larger total number of moles of C.
D. The system at 298.15 K will have a lower mole fraction of C in the vapor phase and a higher mole fraction of C in the liquid phase than the one at 423.15 K. But it is unclear which will have a larger total number of moles of C.
E. None of these is definitely accurate.
