Chemical kinetics
Chemical kinetics
Chemical kinetics (pronunciation: /ˈkɛmɪkəl kɪˈnɛtɪks/), also known as reaction kinetics, is the study of rates of chemical processes.
Etymology
The term "chemical kinetics" is derived from the Greek words khemikos meaning "relating to chemistry," and kinesis meaning "movement."
Definition
Chemical kinetics involves the use of experimental data to formulate models that predict the rates of chemical reactions. The rate of a chemical reaction is affected by several factors such as temperature, pressure, concentration of reactants, and the presence of catalysts.
Related Terms
- Rate of Reaction: The speed at which reactants are converted into products in a chemical reaction.
- Reaction Mechanism: The step-by-step sequence of reactions by which the overall chemical change occurs.
- Catalyst: A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
- Activation Energy: The minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
Applications
Chemical kinetics has applications in various fields such as chemical engineering, material science, pharmaceuticals, and environmental science. It is used to understand and predict the outcomes of chemical reactions, which is crucial in the development of new drugs, materials, and environmental policies.
