What Factors Affect the Rate of A Reaction? By Jade Hill A chemical reaction occurs when two-reactant particles collide with sufficient energy, facing each other in the correct direction. There is always a transfer of energy and a new product formed. There is some times a change in the appearance of the new product. If chemical reactions did not take place there would only be about 100 different substances in the world. All other materials are created by chemical reactions. Mass is not loss when reactants become products. During a reaction bonds in the reactants are broken (energy required) and bonds in the product are formed (energy required). Reactions always involve a change/transfer in energy. The reactants always give out or take in energy. This is usually in the form of heat energy. Reactions involving a change/transfer of energy can be put into two categories - Endothermic reactions: - require energy to proceed and will...
