For a pure substance, the following data at saturated conditions are given:
ln 𝑃sat (bar) 𝑇 (K)
0.693 350
1.386 370
Assume that the vapor phase behaves ideally, the molar volume of the liquid is negligible, and the latent heat of vaporization is constant over the given temperature range. The universal gas constant, 𝑅 = 8.314 J K-1 mol-1. From the above data, the estimated latent heat of vaporization at 360 K is ____________ kJ/mol (rounded off to one decimal place).
