Do it yourself idiot.
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
This energy can be transformed in heat, light (chemiluminescence, bioluminescence), rarely in sounds etc.
it lowers the amout of activation energy needed to start the reaction.
Energy is released during a decomposition reaction.
During an exothermic reaction, energy is released in the form of heat to the surroundings. This results in an increase in temperature, making the surroundings warmer. Exothermic reactions typically involve the breaking of bonds in reactants and the formation of new bonds in products, releasing energy in the process.
An endergonic reaction is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed. To view the source and read more about endergonic reactions go to: http://en.wikipedia.org/wiki/Endergonic_reaction
