List of top Mass Transfer Questions on Liquid-liquid extraction

Water in a container at 290 K is exposed to air containing \(3\ %\) \(\mathrm{CO_2}\) by volume. Air behaves like an ideal gas and is maintained at \(100\ \text{kPa}\) pressure. The liquid phase comprising of dissolved \(\mathrm{CO_2}\) in water behaves like an ideal solution. Use Henry’s constant of \(\mathrm{CO_2}\) dissolved in water at 290 K as \(12\ \text{MPa}\). Under equilibrium conditions, which one of the following is the CORRECT value of the mole fraction of \(\mathrm{CO_2}\) dissolved in water?

Feed solution F is contacted with solvent B in an extraction process. Carrier liquid in the feed is A and the solute is C. The ternary diagram depicting a single ideal stage extraction is given below. The dashed lines represent the tie-lines.

The CORRECT option(s) is/are
