Single Equilibrium Stage In gas-liquid system, the solute A is in the gas phase V , along with inert gas B, while inert solvent C (water) is in the liquid phase L . Gas B (inert) is assumed to be insoluble in solvent C (water) and the water C does not vaporize to gas phase, after equilibrium.
Single Equilibrium Stage x B0 = 0.0, y C2 = 0.0 y C1 = 0.0, x B1 = 0.0

• Summer '19

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
