Methanol has a normal boiling point of 64.6 °C at 760 torr. The △Hvap = 35.2 kJ/mol. What is the vapor pressure of methanol at 12.0 °C? ln (P2P1) = −△HvapR (1T2 − 1T1)R = 8.314 J /mol⋅K
The vapor pressure of ethanol is 1.00 x 102 mmHg at 34.90oC. What is its vapor pressure at 51.73 oC? (ΔHvap for ethanol is 39.3 Kj/mol.) Given the vapor pressure at one temperature, P1, we can calculate the vapor pressure at a second temperature, P2. In (P1/P2) = ΔHvap/R (1/T2 - 1/T1) Where, ΔHvap for ethanol must have the units of J/mol. R = 8.314 J/K.mol .. The temperatures must be in Kelvins. Solve for P2, What is the vapor...
