Energy in Chemical Reaction
   D energy
            release - in the form of heat - exothermic
            absorb - in the form of the absence of heat - Endothermic

     Getting reaction started
            activation energy
                minimum amount of energy needed to start a reaction

    Rate of CHemical Reaction
            1.  concentration - amount of material in given volume
            2.  surface area - smaller pieces - more surface area
            3.  temerature - add heat
            4.  catalysis - decrease the amount of  needed activiation energy
                        the faster the reaction
                                a.  enzymes - biological catalyst
                                    i.  lower temp. needed for reaction
                                    ii break away unchanged

                                b.  inhibitors
                                    i.  slows down reactions - decrease the rate of reaction
