The Antoine equation for the vapor pressure of a liquid at a given temperature is given by p* = eA-B/(T + C) The constants for benzene are A = 15.9008 B = 2788.51°C C = 220.80°C for the vapor pressure in millimeters of mercury (mmHg). Linearize the equation about a temperature of 40°C. Compare the actual vapor pressure (from the Antoine equation) at 45 and 60°C with the vapor pressure calculated from the linearized equation. What is the percent difference in each case? Comment on the suitability of the linearized equation.
