In physics and engineering, kinetics is the branch of classical mechanics that is concerned with the relationship between the motion and its causes, specifically, forces and torques.
1. a. : a branch of science that deals with the effects of forces upon the motions of material bodies or with changes in a physical or chemical system. b. : the rate of change in such a system. 2. : the mechanism by which a physical or chemical change is effected. Examples of kinetics in a Sentence. Recent Examples on the Web.
kinetics, branch of classical mechanics that concerns the effect of forces and torques on the motion of bodies having mass. Authors using the term kinetics apply the nearly synonymous name dynamics (q.v.) to the classical mechanics of moving bodies.
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 – area of chemistry dealing with speeds/rates of reactions. rates of reactions affected by four factors concentrations of reactants; temperature at which reaction occurs; presence of a catalyst; surface area of solid or liquid reactants and/or catalysts
The study of chemical kinetics concerns the second and third questions—that is, the rate at which a reaction yields products and the molecular-scale means by which a reaction occurs. In this module, we will examine the factors that influence the rates of chemical reactions, the mechanisms by which reactions proceed, and the quantitative ...
Chemical kinetics is the study of rates of chemical processes and includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information …
In Unit V, we consider the speed, or rate, of chemical reactions. Thermodynamics tells us if a particular reaction will be spontaneous, but not how fast it will occur. Thus, both thermodynamics and kinetics are necessary for understanding chemical reactions.
The study of reaction rates, called chemical kinetics, encompasses a wide range of activities, measurements, and calculations.
This lecture provides an introduction to kinetics and shows one of the coolest reactions known: the oscillating clock reaction. Watch as colors change quickly as different steps in the reaction become spontaneous.
