Partial molar properties describe how the properties of a solution change with the addition of an infinitesimal amount of a component, reflecting its contribution to the overall mixture. They are crucial for understanding the behavior of mixtures, especially in non-ideal solutions, and are used to calculate properties like volume, enthalpy, and Gibbs energy of mixing.

Non-ideal solutions deviate from Raoult's law due to interactions between different molecules that are not identical to those in the pure components, leading to changes in vapor pressure. These deviations are caused by differences in intermolecular forces such as hydrogen bonding, dipole-dipole interactions, or Van der Waals forces, resulting in either positive or negative deviations from ideal behavior.

properties like volume

Enthalpy is a thermodynamic property that represents the total heat content of a system, combining its internal energy with the product of its pressure and volume. It is a useful concept for understanding heat exchange in constant-pressure processes, such as those occurring in many chemical reactions and phase changes.
