TīmeklisVapor pressure(or vapour pressurein English-speaking countries other than the US; see spelling differencesand equilibrium vapor pressure) is defined as the pressureexerted by a vaporin thermodynamic equilibriumwith its condensedphases(solid or liquid) at a given temperature in a closed system. Raoult's law is a phenomenological relation that assumes ideal behavior based on the simple microscopic assumption that intermolecular forces between unlike molecules are equal to those between similar molecules, and that their molar volumes are the same: the conditions of an ideal solution. This … Skatīt vairāk Raoult's law is a relation of physical chemistry, with implications in thermodynamics. Proposed by French chemist François-Marie Raoult in 1887, it states that the partial pressure of each component of an Skatīt vairāk Raoult's law was first observed empirically and led François-Marie Raoult to postulate that the vapor pressure above an ideal mixture of liquids is equal to the sum of the vapor pressures of each component multiplied by its mole fraction. Taking compliance with … Skatīt vairāk In many pairs of liquids, there is no uniformity of attractive forces, i.e., the adhesive (between dissimilar molecules) and cohesive forces (between similar molecules) are … Skatīt vairāk • Antoine equation • Atomic theory • Azeotrope • Dühring's rule Skatīt vairāk
