# Volume partial molar

## I am getting negative partial molar volume (PMV) of a solute solvated in a supercritical fluid at infinite dilution. The nature of interaction of entire system is purely van der Walls interaction.

Jun 06, 2017 · The partial molar volume is determined for an ethanol water mixture over the entire mole fraction range. The method used is to fit an equation to data that consist of Molar volume vs mole fraction pmolar - University of Kansas The negative partial molar volume means that adding salt to water will decrease the volume of the system. The final state, water+salt, will have a lower volume than the water itself - see example b. Chemical Thermodynamics 8.1 - Partial Molar Quantities ... Sep 14, 2016 · Partial molar quantities for a substance are the partial derivative of that quantity with respect to the number of moles of that substance at constant temperature, pressure, and number of … How can we explain the negative partial molar volume?
