Science > Chemistry > Chemical Thermodynamics and Energetics > Gibb’s Energy and Spontaneity The Concept of Gibb’s Free Energy (G): By the second law of thermodynamics, STotal = ΔSSystm + ΔSSurroundings Thus to decide spontaneity of the process we have to determine the change in entropy of the system and the change in entropy of the surroundings.

Science > Chemistry > Chemical Thermodynamics and Energetics > Concept of Entropy of a System In this article, we shall study the concept of entropy and its relation with the spontaneity. Spontaneous Process: The spontaneous process is defined as a process that takes place on its own without external influence. A spontaneous process does not […]
Science > Chemistry > Chemical Thermodynamics and Energetics > Introduction Chemical Thermodynamics and its Scope: Energy stored in chemical substances is called chemical energy. Thermodynamics is the branch of science that deals with the different forms of energy, the quantitative relationships between them and the energy changes that occur in the physical and chemical process.
