Vapor pressure: 12.7 kPa (25 °C) 24.4 kPa (40 °C) 181 kPa (100 °C) [8] Conjugate acid: ... Benzene is an organic chemical compound with the molecular formula C 6 H 6.
Vapor pressure of liquid and solid benzene. Equilibrium vapor pressure can be defined as the pressure reached when a condensed phase is in equilibrium with its own vapor. In the case of an equilibrium solid, such as a crystal, this can be defined as the pressure when the rate of sublimation of a solid matches the rate of deposition of its vapor ...
Values are given in terms of temperature necessary to reach the specified pressure. Valid results within the quoted ranges from most equations are included in the table for comparison. A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875).
A low-pressure parameter set is used to describe the vapour pressure curve up to the normal boiling point and the second set of parameters is used for the range from the normal boiling point to the critical point. Typical deviations of a parameter fit over the entire range (experimental data for Benzene)
where p* is the vapor pressure of the pure component. At first sight, Raoult's law appears to be a special case of Henry's law, where H v px = p*. This is true for pairs of closely related substances, such as benzene and toluene, which obey Raoult's law over the entire composition range: such mixtures are called ideal mixtures.
The restaurant opened on October 8, 1990, in Shenzhen's special economic zone. The South China Morning Post reported that on its opening day, the unique McDonald's received over 40,000 customers ...
Raoult's law (/ ˈ r ɑː uː l z / law) is a relation of physical chemistry, with implications in thermodynamics.Proposed by French chemist François-Marie Raoult in 1887, [1] [2] it states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component (liquid or solid) multiplied by its mole fraction in the mixture.
