WebQuestion: The vapor pressure P (in bar) of a liquid with a molar mass of 63.9 g mol-1 varies with temperature T according to the following equation, ln P = 7.19 × 10-3 - 1.88 T-1 - 4.173 T-2. The densities of the liquid and vapor phases are 0.819 g mL-1 and 3.15 × 10-4 g mL-1, respectively. Calculate the molar enthalpy of vaporization ( DvapH) at the normal boiling WebSublimation is the phase change from solid to gas without going through a liquid phase. (Solid CO2, called dry ice, is an example of one substance that sublimes.) Use Hess’s law to show that the enthalpy of sublimation, DsubH, is equal to DfusH 1 DvapH. Question: Sublimation is the phase change from solid to gas without going through a liquid ...
WebDetermine the standard Gibbs free energy change, rG, for the reactions of liquid methanol, of CO(g), and ofethyne, C2H2(g), with oxygen gas to form gaseous carbondioxide and (if hydrogen is present) liquid water at298 K.

WebSince DvapH is positive, vapor pressure always increases as temperature increases. I. Clausius-Clapeyron The vapor pressure for any one liquid increases exponentially with increasing T The vapor pressure of one liquid compared to another depends inversely on DvapH The boiling point of any liquid depends on the external pressure.
