I)
Chemical reactions occur because the products of the reaction have
less energy than the reactants. (Drive toward less energy). These
reactions release energy into the environment, like the burning
of a
match. Click on the picture to further examine energy changes in reactions |

II) Chemical
reactions also occur because the products are more random (less
ordered) than the reactant . (Drive toward greater entropy) Click on the picture to further examine entropy changes in reactions. |
