Background
The chemical reaction rate means how fast the chemical reaction proceeds. Generally expressed as a change (decrease or increase) in the concentration of a reactant or a product per unit time, the reaction rate is related to the nature and concentration of the reactant, the temperature, the pressure, the catalyst, etc., and, if the reaction is carried out in solution, the nature and amount of the solvent. Where the pressure relationship is small (except for gas reactions) and the catalyst effect is large. The reaction rate can be controlled by controlling the reaction conditions to achieve certain objectives. Measuring the rate of a chemical reaction requires determining the change in the concentration of a substance over a unit of time around a certain time. However, in general, a chemical reaction is still in progress during measurement, and there is a difficulty in determining the reaction rate using a general chemical analysis method. An approximation is to stop the reaction immediately, if at all, and to make it very slow, for example by dilution, cooling, addition of inhibitors or removal of catalysts, for chemical analysis. However, this is time consuming, laborious, inaccurate and has limited reactions that can be studied. A widely used method is to measure properties of a substance, such as pressure, conductivity, absorbance, etc., by which a continuous determination is achieved in relation to the concentration of the substance.
