Unformatted text preview: randomly. However, the rate of a chemical reaction at normal earth temperatures may be so slow that it is imperceptible. No matter how energetically favorable a chemical reaction is, some energy is needed to get the reaction started. This energy is called the activation energy. Activation energy is anything that increases the rate at which the reactants collide (or come together) so that any reaction can occur. Some chemical reactions occur naturally because the activation energy needed to break the bonds of the reactants can be supplied by ambient heat energy. Most reactions cannot, which is a good thing for life. Reasonably unstable molecules such as nucleic acids and proteins would degrade spontaneously if just a small amount of heat energy was needed to overcome the activation energy....
