The vapor pressure of benzene between 10 °C and 30 °C fits the expression log(p/Torr) = 7.960 - (1780/T). Calculate (i) the enthalpy of vaporization and (ii) the normal boiling point of benzene.

Step 1
(i) The enthalpy of vaporization (ΔHvap) can be calculated using the Clausius-Clapeyron equation, which is: ln(P2/P1) = -ΔHvap/R * (1/T2 - 1/T1) In this case, the equation given is in the form of log(P) = A - B/T, which is a rearranged form of the Show more…

The heat of vaporization of benzene, $\mathrm{C}_{6} \mathrm{H}_{6}(l)$, is $30.72 \mathrm{~kJ} \cdot \mathrm{mol}^{-1} .$ Given that the vapor pressure of benzene is $404.5$ Torr at $60.0^{\circ} \mathrm{C}$, calculate the normal boiling point of benzene.
The enthalpy of vaporization of benzene is 31.0 kJ/mol. At 26°C, the vapor pressure of benzene is 100 torr. Calculate the vapor pressure of benzene at 65°C.
