Question

In the analysis of freezing point depression, general chemistry students use the equation: ΔT = K_f m. Where did this equation come from? Work through the same analysis as we did in class for boiling point elevation. Watch out for G(s) – G(l) = -ΔG fusion (in the boiling point elevation analysis, it was +ΔG vaporization). This means that ΔT = T* - T for freezing point remembering that it meant T – T* in the boiling point analysis. Also prove that Kf = 1.86 ^oC kg mol^-1
