In most basic chemistry courses a kinetic approach is used to explain the vapor pressure lowering for solutions with a non volatile solute. This approach has been considered intrinsically incorrectfor many years based on several objections. We consider that these objections are based on a ...
It decreases with the addition of a nonvolatile solute because the solvent constitutes a smaller proportion of the liquid, and the nonvolatile solute occupies space without contributing to vapor pressure. The greater the concentration of solute, the greater is the reduction in vapor pressure. View ...

(FEI, USA) with primary energy of 10 keV and operating pressure of 5 × 10−6 Torr and constructed by Nova NanoSEM software (version 1.3.1). FTIR spectra were recorded with a liquid nitrogen-cooled (MCT) Spectrum 100 FTIR Spectrometer (PerkinElmer, USA) equipped with an ...
The equilibrium vapor pressure is an indication of the evaporation rate of a liquid. A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The vapor pressure of any substance increases nonlinearly with temperature and the atmospheric boiling point of a ...
