Understanding Gibbs Free Energy Change Qualitatively

Gibbs free energy is a measure of the spontaneity of a reaction. Basically, a process that can occur under a particular set of conditions is said to be spontaneous; a process that cannot occur under the given conditions is nonspontaneous.

Although a reaction may be spontaneous, it may not occur at an observable rate. The speed of a reaction involves kinetics, not thermodynamics. Gibbs free energy is not a kinetic term, it is a thermodynamic term.

Kinetics is related to the "activation energy" of a reaction, i.e. the amount of energy required to move the reactants "up the energy hill" to the ...
