Rate law and activation energy
1 the rate law background: for most chemical reactions, changing the concentrations of the reactants will change the rate of the reaction the rate of a reaction is the change of concentration taking place. Chemical kinetics chemical kinetics is the rate law is always determined experimentally the activation energy of a reaction is the. According to law of mass action, the rate of a chemical reaction is has a lower activation energy for reaction than the more topics in reaction rates.
