Cs2 is a commonly used nonpolar solvent but its vapor when inhaled can cause negative acute and chronic health effects. cs2 is known to have a vapor pressure of 0.450 mpa at 100 °c and 0.782 mpa at 125 °c. (a) estimate the heat of vaporization and normal boiling temperature of cs2 based on the given pressure data. (b) using the given vapor pressures and considering t, = 0.7 to estimate the acentric factor w for cs2 whose critical temperature and pressure are 552 k and 7.800 mpa, respectively. (c) the normal boiling temperature of cs2 is 46.3 °c. now use the pitzer-type lee-kesler correlation to estimate its a.
