A tank contains a mixture of water and carbon dioxide. The mol fraction of CO 2 in

Question:

A tank contains a mixture of water and carbon dioxide. The mol fraction of CO₂ in the liquid is 5.0 × 10₋₄ and the temperature is 70 °C.

a) Calculate the total pressure as well as the composition of the vapor phase.

b) To what temperature should you bring the system in order to increase the mol fraction of CO₂ in the liquid by a factor of 5, if the total pressure is to remain constant?

c) Calculate the composition of the vapor phase for the conditions of part (b). Henry’s constant of CO₂ is k=9.12 x 10-32400/T (bar kg/mol).
