alleryElevation in boiling point ΔT_b for solution of non-volatile solute:
AIndependent of m
BK_b × M
CK_b × x
DK_b × m (K_b = ebullioscopic constant, m = molality)
Answer & Solution
Correct answer: D. K_b × m (K_b = ebullioscopic constant, m = molality)
ΔT_b = K_b × m.
K_b is solvent-specific molal elevation constant.
e.g., for water K_b = 0.52 K kg/mol.
Used to determine molar mass from BP measurement.
