WebDec 2, 2024 · The field of chemical kinetics developed from the law of mass action, formulated in 1864 by Peter Waage and Cato Guldberg. The law of mass action states the speed of a chemical reaction is proportional to the amount of reactants. Jacobus van't Hoff studied chemical dynamics. WebFirst Order rate = k[A]1 = k[A] The rate is directly proportional to the concentration. If you double the concentration, you double the rate. If you triple the concentration, you triple the rate. If you halve the concentration, you halve the rate, and so on. Second Order rate = k[A]2 The rate is proportional to the square of the concentration.
