Suppose you are working on the separation of ammonia from air using pure water, and you want to find the slope of the equilibrium curve (m). The inlet gas contains 1 mol% ammonia, and the outlet gas contains 0.27 mol% ammonia. You found that an absorption column with exactly 4 equilibrium stages is required to achieve this separation. The column operates isothermally at 80 F and isobarically at 1 atm. The ratio of L/V = 1.2, and is constant. Assuming that equilibrium is of the form y = mx, calculate the value of m.
