Tabulated values from literature for the latent heat of benzene in J/g are provided in the table below at 25°C and the normal boiling temperature (353.2K). Substance ΔH at 25°C (298.15 K) ΔHn at 353.2K Benzene 433.3 J/g 393.3 J/g Determine: A. The latent heat of vaporization at Tn using the Watson equation from the tabulated value at 25°C. B. The latent heat of vaporization at Tn using the Riedel equation. Note: Calculate the percentage error in each case! Data: For benzene: Molar mass = 78.114g, Tc = 562.2K, and Pc = 48.98 bar.
