Crystallization - Definition, Process, Types and Examples

Crystallization is a natural process which happens when the materials solidify from a liquid, or as they precipitate out of a liquid or gas. This process can be carried out by causing a physical change, like a change in temperature, or a chemical change like acidity. The crystallization process is carried out on the basis of the size and shapes

Thermodynamics and Kinetics - Stanford University

This is the difference between thermodynamics and kinetics. Thermodynamics can tell you only that a reaction should go because the products are more stable (have a lower free energy) than the reactants. Another way of saying this is that the reaction has a negative free energy change: DG is negative and therefor the reaction is spontaneous. Yet
