Reaction potential.

Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called endergonic reactions. In this case, the products, or final state, have more free energy than the reactants, or initial state. The electrodes with a voltage difference are put in the etching solution (electrolyte) to generate an electric field. By controlling the voltage difference (etching potential) within the range of the reaction potential between the A layer and the M layer, the selective removal of the A atomic layer in the MAX phase can be achieved.AboutTranscript.
