It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical … See more The pioneering work of chemical kinetics was done by German chemist Ludwig Wilhelmy already 1850. He studied experimentally the rate of inversion of sucrose and he used integrated rate law for the … See more The experimental determination of reaction rates involves measuring how the concentrations of reactants or products change over time. For example, the concentration of a … See more In general terms, the free energy change (ΔG) of a reaction determines whether a chemical change will take place, but kinetics describes how fast the reaction is. A reaction can be very See more The mathematical models that describe chemical reaction kinetics provide chemists and chemical engineers with tools to better … See more Nature of the reactants The reaction rate varies depending upon what substances are reacting.
