Structure and properties. Thermodynamic properties. Spectral data. Vapor pressure of liquid. Density of ethanol at various temperatures. Data obtained from Lange 1967. These data correlate as ρ [g/cm 3] = −8.461834 × 10 −4 T [°C] + 0.8063372 with an R2 = 0.99999. Properties of aqueous ethanol solutions. Data obtained from Lange 1967.
At 20.0 °C, the vapor pressure of ethanol is 5.95 kPa, and at 63.5 °C, its vapor pressure is 53.3 kPa. Use this information to estimate the enthalpy of vaporization for ethanol. Answer
24 Φεβ 2023 · Equation \ref{2} is known as the Clausius-Clapeyron Equation and allows us to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known.
1 Ιουλ 2014 · You use the Clausius-Clapeyron equation. Experiments show that the vapour pressure P, enthalpy of vaporization, ΔH_"vap", and temperature T are related by the equation lnP = "constant" – (ΔH_"vap")/"RT" where R is the ideal gas constant.
For several substances, such as water, values are shown for two standard states, (1) and (g). The relation between these is shown in Example 12.7. The standard states in Table A.8 are (g), pure ideal gas at. 1 bar; (l) and (s), the normal state of that substance at 1 bar.
1 Αυγ 2010 · Extended properties include density, vapor pressure, surface tension, viscosity, molar and specific heat capacity, enthalpy of vaporization, thermal conductivity and static relative permittivity (dielectric constant) of ethanol.
