What is fugacity ? I know it the corrected pressure for non ideal systems , but I need a much more intuitive sense of the term. It would be nice to get some help on this...

Fugacity is a measure of the tendency of a substance to escape or flee from a system. It is also referred to as the escaping tendency or escaping tendency coefficient.
Fugacity is directly proportional to pressure and inversely proportional to temperature. As pressure increases, fugacity also increases. However, as temperature increases, fugacity decreases.
Fugacity takes into account the non-ideality of a substance, while partial pressure assumes ideal behavior. This means that fugacity is a more accurate measure of a substance's escaping tendency in a real system.
Fugacity is used in thermodynamics to calculate the equilibrium conditions for a non-ideal system. It is also used in the calculation of chemical potential, which is an important property in determining the thermodynamic stability of a system.
Fugacity cannot be measured directly, but it can be calculated using equations such as the fugacity equation or the Van der Waals equation. It can also be estimated using experimental data and empirical correlations.
