Chemical Kinetics

The area of physical chemistry that deals with comprehending the speeds of chemical processes is known as chemical kinetics, sometimes known as reaction kinetics. In contrast, chemical thermodynamics addresses the direction in which a reaction takes place but does not address the pace of the process. Chemical kinetics is the study of how experimental circumstances affect a chemical reaction's rate and reveal details about its mechanism and transition stages. It also involves the development of mathematical models that may be used to represent the properties of a chemical process. The reactant's physical state (solid, liquid, or gas) has a significant role in determining the rate of change. Thermal motion brings reactants into touch when they are in the same phase, such as in aqueous solution. The reaction, however, is only possible when the phases are in contact with one other. Only when they come into touch, or at the surface of a liquid in the case of a gas and a liquid, can a reaction take place. For the reaction to fully develop, vigorous shaking and stirring may be required. The more evenly distributed a solid or liquid reactant is, the bigger its surface area per unit volume and the more contact it has with the other reactant, leading to a quicker reaction.
