2024年11月8日 · Chemical kinetics, the branch of physical chemistry that is concerned with understanding how fast or how slow chemical reactions occur (that is, their rates). The principles of chemical kinetics apply to purely physical processes as well as to chemical reactions.
Chemical kinetics - Wikipedia
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions.

2023年8月26日 · The study of chemical kinetics concerns the rate at which a reaction yields products and the molecular-scale means by which a reaction occurs. In this chapter, we will examine the factors that influence the rates of chemical reactions, the mechanisms by which reactions proceed, and the quantitative techniques used to determine and describe the ...

Chemical Kinetics helps us to understand how chemical reactions occur. Chemistry, by its very nature, is concerned with change. Substances with well defined properties are converted by chemical reactions into other substances with different properties. For any chemical reaction, chemists try to find out.
Chemical Kinetics. Kinetics – how fast does a reaction proceed? Thermodynamics – does a reaction take place? Reaction speed: measured by the change in concentration with time. Important factors which affect rates of reactions: reactant concentration. temperature. action of catalysts. surface area. pressure of gaseous reactants or products.
In this chapter, we will examine the factors that influence reaction rates, and in later chapters, we will explore the strategies that living systems use to increase and control those rates. Reaction rates are determined by the frequency, orientation, and energy with which molecules collide.
