The plot given below shows ๐ โ ๐ curves (where P is the pressure and T is the temperature) for two solvents X and Y and isomolal solutions of NaCl in these solvents. NaCl completely dissociates in both the solvents.
On addition of equal number of moles of a non-volatile solute S in equal amount (in kg) of
these solvents, the elevation of boiling point of solvent X is three times that of solvent Y.
Solute S is known to undergo dimerization in these solvents. If the degree of dimerization is
