Spontanreaktion
Spontanreaktion is a German term that translates to spontaneous reaction in English. It refers to a chemical or physical process that occurs naturally without external intervention once initiated. In thermodynamics, a spontaneous process is one that has a negative change in Gibbs free energy (ΔG < 0) under constant temperature and pressure. This indicates that the process is thermodynamically favorable and will proceed in the forward direction without continuous energy input.
The spontaneity of a reaction is determined by two main factors: enthalpy change (ΔH) and entropy change
It is important to distinguish between spontaneity and reaction rate. A spontaneous reaction may be very slow
