First order chemistry

WebA first order reaction is a chemical process in which the rate of the reaction is proportional to the concentration of the reactant. In other words, if the concentration doubles, so do the pace of the reaction. Like the decomposition reaction, a first-order reaction can include just one reactant or up to two.
