For Figure 13-23 suppose we desired to obtain the desired raffinate concentration with exactly two equilibrium stages. This can be accomplished by changing the amount of solvent used. Would we want to increase or decrease the amount of solvent? Explain the effect this change will have on M, EN, , and the number of stages required
