alleryElevation of boiling point (ΔT_b) is related to molality (m) by:
AΔT_b = K_f × m
BΔT_b = K_b × m
CΔT_b = K_b × M
DΔT_b = K_b / m
Answer & Solution
Correct answer: B. ΔT_b = K_b × m
**ΔT_b = K_b × m**, where K_b is the molal boiling point elevation constant (ebullioscopic constant), units K kg mol⁻¹.
