In this problem you will be calculating and plotting the saturation pressure of 4 components: n- pentane, n-hexane, benzene, and ethanol using a variety of methods. Produce 4 graphs (one for each component) where the vapor pressure is calculated from 350 - 400 K using the three approaches below (3 curves per plot): a. Antoine's equation (i.e., experimental data) b. The Clausius-Clapeyron equation assuming the heat of vaporization is constant at 350 K c. Using the Peng-Robinson equation of state.
