HW 3 - p 4.64 - Absorption of Ammonia in Water- 8 pts
A vapor mixture having equal volumes of NH3 and N2 is to be contacted at 20 oC and 1 atm with water to absorb a portion of NH3. If 14 m3 of this mixture is brought into contact with 10 m3 of water and if equilibrium is attained, calculate the percent of the ammonia originally in the gas that will be absorbed. Both temperature and pressure will be maintained constant during absorption.

So, I get all the way to the end of this problem. My negative slop is ridiculously. Then, I make an equation between (0,0) and the first point on my equilibrium curve. Two equations, two knowns, good. Okay, now I have those two unknowns, X and Y. What do I do with them now? How do I get from those values to 99.whatever% NH3 absorbed?

The % of NH3 absorbed is the ratio of the molar flow rate of NH3 leaving in the liquid phase to the molar flow rate of NH3 entering in the feed gas...times 100%.
