The Antoine Equation can be used to estimate vapor pressure at various temperatures for different substances using sets of empirically-derived constants. The equation can be written as: log10 ? = ? − (? /(? + ?)) Where for water A = 8.07131, B = 1730.63, C = 233.426, T = temperature [°C], and P = vapor pressure [mmHg]. Note that with these constants the temperature and pressure must be provided in °C and mmHg, respectively. Feel free to compare this to values provided in your book or online Using the Antoine Equation and the provided constants, what atmospheric pressure (provided in terms of % of standard atmospheric pressure) will permit water to boil at 75 °C?
