The plot given below shows p T curves where p is the pres sure 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 760 Pressure mmHg 360 362 2 3 4 367 368 1 solvent X 2 solution of NaCl in solvent X 3 solvent Y 4 solution of NaCl in solvent Y Temperature K On addition of equal number of moles of a non volatile sol ute 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 dimerisation in these solvents If the degree of dimerisation is 0 7 in solvent Y the degree of
