Web29 mei 2024 · Vapor Pressure and Temperature Vapor pressure is dependent upon temperature. When the liquid in a closed container is heated, more molecules escape the … WebWe will now see and understand how this lowering in vapour pressure is determined mathematically. Let us assume a binary solution in which the mole fraction of the solvent be x 1 and that of the solute be x 2, p1 be the vapour pressure of the solvent and p 1 o be the vapour pressure of the solvent in pure state. According to Raoult’s Law:
WebAccording to this equation, the rate at which the natural logarithm of the vapor pressure of a liquid changes with temperature is determined by the molar enthalpy of vaporization of the liquid, the ideal gas constant, and the temperature of the system.
