A 1.00 molal aqueous solution of trichloroacetic acid (CCl₃COOH) is heated to its boiling point. The solution has the boiling point of 100.18°C. Determine the van’t Hoff factor for trichloroacetic acid. (K_b for water = 0.512 K kg mol^-1)

0.3

As ΔT_b = iK_bm
(100.18 – 100)°C = i × 0.512 K kg mol^-1 × 1 m
0.18 K = i × 0.512 K kg mol^-1 × 1 m
∴  i = 0.3
