Diffusion equilibrium is reached when the concentrations of the diffusing substance in the two compartments becomes equal. In Chemistry, concentration is the measure of how much of a given substance there is mixed with another substance Diffusion is the net movement of particles (typically molecules from an area of high concentration to an area of low concentration by uncoordinated random movement

Consider two systems; S1 and S2 at the same temperature and capable of exchanging particles. Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature In Chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two Atoms in a definite arrangement held together by If there is a change in the potential energy of a system; for example μ12 (μ is Chemical potential) an energy flow will occur from S1 to S2, because nature always prefers low energy and maximum entropy. Potential energy can be thought of as Energy stored within a physical system In Thermodynamics and Chemistry, chemical potential, symbolized by μ, is a term introduced by the American engineer chemist and mathematical In Physics and other Sciences energy (from the Greek grc ἐνέργεια - Energeia, "activity operation" from grc ἐνεργός In Thermodynamics (a branch of Physics) entropy, symbolized by S, is a measure of the unavailability of a system ’s Energy
