WebbIn brief summary: Thermodynamics tells us that a reaction should go if the products are more stable (have a lower free energy) than the reactants --- the reaction has a negative free energy change. Kinetics, on the other hand, tells us how fast the reaction will go, though doesn't tell us anything about the final state of things once it gets there.
