order of a reaction — a number that relates the rate of a chemical reaction with the concentrations of the reacting substances : the sum of all the exponents of the terms expressing concentrations of the molecules or atoms determining the rate of the reaction compare… … Useful english dictionary
Order of reaction — In chemical kinetics, the order of reaction with respect to certain reactant, is defined as the power to which its concentration term in the rate equation is raised [1]. For example, given a chemical reaction 2A + B → C with a rate equation r =… … Wikipedia
reaction — 1. The response of a muscle or other living tissue or organism to a stimulus. 2. The color change effected in litmus and certain other organic pigments by contact with substances such as acids or alkalies; also the property that such substances… … Medical dictionary
Reaction–diffusion system — Reaction–diffusion systems are mathematical models which explain how the concentration of one or more substances distributed in space changes under the influence of two processes: local chemical reactions in which the substances are transformed… … Wikipedia
Zero Moment Point — is a concept related with dynamics and control of legged locomotion, e.g., for humanoid robots. It specifies the point with respect to which dynamic reaction force at the contact of the foot with the ground does not produce any moment, i.e. the… … Wikipedia
Reaction rate constant — In chemical kinetics a reaction rate constant k or λ quantifies the speed of a chemical reaction.[1] For a chemical reaction where substance A and B are reacting to produce C, the reaction rate has the form: Reaction: A + B → C k(T) is the… … Wikipedia
reaction, heat of — Amount of heat that must be added or removed during a chemical reaction to keep all substances involved at the same temperature. If it is positive (heat must be added), the reaction is endothermic; if it is negative (heat is given off), the… … Universalium
