Rate equation - Wikipedia
WEBIn chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only. [1]
17.1: Rates of reactions and rate laws - Chemistry LibreTexts
WEBNov 13, 2022 · The relation between the rate of a reaction and the concentrations of reactants is expressed by its rate law. For example, the rate of the gas-phase decomposition of dinitrogen pentoxide \[2N_2O_5 → 4NO_2 + O_2\] has been found to be directly proportional to the concentration of \(N_2O_5\): \[\text{rate} = k [N_2O_5]\]

WEBrate law (also, rate equation): mathematical equation showing the dependence of reaction rate on the rate constant and the concentration of one or more reactants. reaction order: value of an exponent in a rate law, expressed as an ordinal number (for example, zero order for 0, first order for 1, second order for 2, and so on)
Reaction Rate Constant: Definition and Equation - ThoughtCo
WEBJan 2, 2021 · The rate constant is a proportionality factor in the rate law of chemical kinetics that relates the molar concentration of reactants to reaction rate. It is also known as the reaction rate constant or reaction rate coefficient and is indicated in an equation by the letter k. Key Takeaways: Rate Constant.
Reaction rate constant - Wikipedia
WEBIn chemical kinetics, a reaction rate constant or reaction rate coefficient ( ) is a proportionality constant which quantifies the rate and direction of a chemical reaction by relating it with the concentration of reactants. [1] For a reaction between reactants A and B to form a product C, a A + b B → c C. where. A and B are reactants.
