Explain why organic reactions occur at a slower rate than inorganic reactions. what do chemists use to speed these reactions up? why doesn't this change the products of the reaction?

The organic particles  are molecules. Because of strong covalent bonding in the molecule, organic compounds do not react quickly. Reactions with organic compounds are generally slower than inorganic reactions due to this fact. 

Increasing temperature speeds up a reaction because of there being more collisions and those collisions have higher energy. Also the high concentration of the chemicals, particle size and there being a suitable catalyst present. ( Though this process is harmful should it be used in modifying results in food grains and meats.)
