Concept explainers
Interpretation:
The Gibbs free energy and required change in enthalpy for a reaction system are to be calculated with given
Concept introduction:
Gibbs Free Energy can be defined as
Here,
When the change in entropy is negligible or zero, the equation changes to the expression:
Second law of thermodynamics tells about the spontaneity of a reaction and Gibbs free energy will tell in which direction the reaction is spontaneous.
It can be expressed mathematically as
