WebVapour Pressure - The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure. Explore more on Liquid State Vapour Pressure, Nature of the liquids, Effect of temperature, boiling point along with heat of vaporization. Visit BYJU'S to learn more about it. WebThe enthalpy of vaporization, ΔHvap, can be determined by using the Clausius-Clapeyron equation (Equation 7.2.5 ): ln(P2 P1) = ΔHvap R ( 1 T1 − 1 T2) Since we have two vapor pressure-temperature values T1 = 34.0oC = 307.2K P1 = 10.0kPa and T2 = 98.8oC = 372.0K P2 = 100kPa we can substitute them into this equation and solve for ΔHvap.
WebJan 5, 2015 · Therefore, when a nonvolatile solute is present, the vapor pressure of the solvent is lower than the vapor pressure of the pure solvent, as illustrated in Figure 13.18." However, this is, I believe, the only textbook which gives this explanation for lowering in vapour pressure on adding a non-volatile solute. WebA liquid’s vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure. Created by Sal Khan. Sort by: Top Voted Questions Tips & Thanks Want to join the conversation?
