Example of rate law expression
WebWrite the rate law expression for a three-step reaction in which one step is a rapid equilibrium, and the other two steps have significantly different magnitudes. ... For an example of a mechanism, consider the … WebIn order to determine the reaction order, the power-law form of the rate equation is generally used. The expression of this form of the rate law is given by r = k[A] x [B] y. In the expression described above, ‘r’ refers to …

The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. For example, the rate law for the elementary reaction 2A + B → products is rate = k[A]² [B]. Created by Jay.
WebA reaction follows an elementary rate law if and only if the (iff) stoichiometric coefficients are the same as the individual reaction order of each species. For the reaction in the previous example (), the rate law would be: if 2NO+O 2 2NO 2 then -r NO = k NO (C NO) 2 C O2 if elementary! See the example below for more examples of rate laws.
WebRate law: The rate law (also known as the rate equation) for a chemical reaction is an expression that provides a relationship between the rate of the reaction and the concentrations of the reactants participating in it.
