What is the regular solution model?
In the regular solution model, the enthalpy of mixing is obtained by counting the different kinds of near neighbour bonds when the atoms are mixed at random; this information together with the binding energies gives the required change in enthalpy on mixing.
What is the difference between real and regular solutions?
Real Systems
These are defined as the difference between the actual free energy (enthalpy, entropy) and the ideal value. The regular solution model gives an enthalpy that is symmetrical with respect to composition, whereas it is often quite unsymmetrical.
What is a regular solution in thermodynamics?
A regular solution is one involving no entropy change when a small amount of one of its components is transferred to it from an ideal solution of the same composition, the total volume remaining unchanged. '' I referred to the possibility of expressing the partial. molal enthalpy ( of component 2) by the Margules.
The Gibbs free energy of a mixture is defined as G=?j?jnj where ?j is the chemical potential of species j, and it is temperature and pressure dependent, and nj is the number of moles of species j.
