Question:

Because solid p-dichlorobenzene, C₆H₄Cl₂ sublimes rather easily, it has been used as a moth repellent. From the data given, estimate the sublimation pressure of C₆H₄Cl₂(s) at 25 °C For C₆H₄Cl₂; mp = 53.1°C; vapor pressure of C₆H₄Cl₂(l) at 54.8 °C is 10.0 mmHg; Δ_fusH = 17.88 kJ mol^-1 ; Δ_vapH = 72.22 kJ mol^-1.
