An entropy-driven reaction is a chemical reaction in which the increase in entropy, or disorder, of the system is the driving force for the reaction to occur. It occurs when there is an overall increase in randomness or number of microstates.

Gibbs Free Energy: The Gibbs free energy (ฮG) determines if a reaction is spontaneous or not by considering both enthalpy and entropy changes.
Second Law of Thermodynamics: This law states that in any spontaneous process, there will always be an overall increase in entropy of both system and surroundings.
Microstates: Microstates refer to different arrangements or configurations that particles can have within a given macrostate.
