logactiviteitcoëfficiënt
Logactiviteitcoëfficiënt, often denoted as γ, is a thermodynamic term that quantifies the deviation of a component's behavior in a non-ideal mixture from that of an ideal solution. In an ideal solution, the activity of each component is simply equal to its mole fraction. However, in real solutions, intermolecular forces between different components are not the same as those between identical components, leading to deviations from ideal behavior.
The logactiviteitcoëfficiënt is the natural logarithm of the activity coefficient, a. The activity coefficient, in turn,
A logactiviteitcoëfficiënt of zero indicates ideal behavior, meaning γ_i = 1. A positive logactiviteitcoëfficiënt (γ_i > 1) signifies
