|
What does Gibbs Free Energy tell us?
|
|
How much energy is given off by a reaction.
|
|
|
The tendency of a reaction to become “random”
|
|
|
How spontaneous a reaction is.
|
Explanation:
Detailed explanation-1: -Gibbs equation helps us to predict the spontaneity of reaction on the basis of enthalpy and entropy values directly. When the reaction is exothermic, enthalpy of the system is negative making Gibbs free energy negative. Hence, we can say that all exothermic reactions are spontaneous.
Detailed explanation-2: -If the Gibbs Free Energy for a process is negative, the process is spontaneous. If the Gibbs Free Energy is positive, the process is non-spontaneous. It is important to point out that spontaneous does not mean fast; in fact, many spontaneous reactions are extremely slow.
Detailed explanation-3: -A spontaneous reaction is one that releases free energy, and so the sign of
