Thermodynamics: Spontaneity, Entropy, and Free Energy

Chapter Seventeen. Thermodynamics: Spontaneity, Entropy, and Free Energy. Introduction. Thermodynamics examines the relationship between heat and work. Spontaneity is the notion of whether or not a process can take place unassisted.

Thermodynamics and Spontaneity

Thermodynamics and Spontaneity. Spontaneous change : the direction of change that does not require work (outside assistance) to bring it about. Spontaneous chemical reactions often are exothermic: Are all exothermic reactions spontaneous (Bertholet C19)?.
