    bonds formed between two ions by the transfer of electrons. The speed at which a chemical reaction proceeds is known as the rate of reaction. The rate of almost every reaction can be increased or decreased due to different factor. Scientists have identified five factors that affect the rate of reaction. The five factors are temperature‚ concentration of the reactants‚ surface area‚ agitation (mixing)‚ and catalyst (chemical helpers). The collision theory states that the rate of a reaction is directly
