E2.15 Enthalpy of Vaporization

Example 2.15: Determine enthalpy of vaporization of benzene at 75 °C. Pitzer's acentric factor, ω = 0.205. Critical temperature, T_c = 561.65 °K

Solution

Reduced temperature, T_r = T/T_c = (75 + 273.15)/561.65 = 0.62

Latent heat of vaporization, ΔH_v (Equation 2.46)
