Which of the following would you NOT expect to increase the total number of moles of C?
The reaction A + B ? C occurs in the vapor phase. It is an exothermic 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. Increasing the pressure at constant temperature. B. Increasing the number of moles of water while leaving P and T constant. C. Increasing the temperature at constant pressure. D. Decreasing the temperature at constant pressure. E. It is impossible to answer the question without specific values of H and K.
