Vapor Pressure Pressure exerted by a gas in equilibrium with its liquid phase at a specific temperature in a closed system. Raoult's Law Describes how the vapor pressure of a solution is related to the mole fraction of the solvent and the pure solvent's vapor pressure. Solvent The component of a solution present in the greatest amount, which dissolves the solute. Solute The substance dissolved in a solvent to form a solution, affecting the solution's vapor pressure. Mole Fraction Ratio of moles of a component to the total moles in a solution, used in calculating vapor pressure. Van't Hoff Factor A factor representing the number of particles a solute dissociates into in a solution. Colligative Properties Properties of solutions that depend on the number of solute particles, not their identity. Equilibrium A state where the rate of vaporization equals the rate of condensation at the liquid's surface. Condensation The process by which a gas turns into a liquid, occurring at the liquid's surface. Vaporization The process by which a liquid turns into a gas, occurring at the liquid's surface. Closed System A system where no matter is exchanged with the surroundings, allowing equilibrium to be studied. Pure Solvent A solvent without any solute, used as a reference in vapor pressure calculations. Solution A homogeneous mixture of solute and solvent, with altered physical properties.
