Consider the evaporation of methanol at 25.0 ?C : CH3OH(l)?CH3OH(g) . Why methanol spontaneously evaporates in open air at 25.0 ?C : Methanol evaporates at room temperature because there is an equilibrium between the liquid and the gas phases. The vapor pressure is moderate (143 mmHg at 25.0 degrees centigrade), so a moderate amount of methanol can remain in the gas phase, which is consistent with the free energy values. A.) Find ?G? at 25.0 ?C . B.) Find ?G...
