Why there are tie lines for 3 phase equilibrium however not for 2-phase equilibrium in a two-component system?
Lever rule derived from mass balance gives the relative amounts of the co-existing phases. It is applied as follows - the tie line is treated as a lever arm, with the fulcrum at the overall composition. For the arm to be horizontal, the weight to be hung at each end must be proportional to the arm length on the other side of fulcrum. Weight at each end corresponds to the amount of the phase at that end. At temperature T and overall composition co, the relative amounts of liquid and the solid phases are determined as follows - Expressing the weight fractions of liquid and solid as fi and fo
