Compare Clausius-Clapeyron and Antoine Equations

This simulation plots the saturation pressure versus temperature predicted by the Clausius-Clapeyron equation for five molecules. The Antoine equation, which is obtained by a fit to experimental data, is also plotted. For water, click “add experimental data” to display data points. The plots of vapor pressure versus temperature are shown over a narrow temperature range near the boiling point at 1-atm pressure (click “near boiling point”) or over a range from the triple point to the critical point (click “extended range”). When log scale is selected, the log of the saturation pressure is plotted versus the inverse temperature.
