An essential aspect of the doctoral project is the modeling of the adjustment of the chemical equilibrium from a substance dynamic point of view. If the metabolic rate (x) and energy turnover of a chemical reaction are considered to be processes, the functional course of the Gibbs enthalpy G (x) in equilibrium reactions always has a minimum. Using spreadsheets, Gibbs enthalpy as a function of G (x) for ester formation, organic acid protonation, isomerization of butane, and almost all other teaching-related events allows prediction of the equilibrium constant K without resorting to the kinetics of equilibrium state to have to. With regard to an experimental realization of processes, the maximum principle of entropy of intuition is often more beneficial than the minimum principle of energy. A free-hand experiment on rubber elasticity should provide access to current concepts such as the entropy force. Entropy forces explain e.g. the swelling capacity of baby diapers as well as the persistence of clouds in the sky. One goal of the PhD project is the development of instructions for students of Chemistry as well as for Chemistry Teachers, taking into account the competences formulated in the core curriculum for chemistry
