Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes this form: rate = k [A] m [B] n [C] p.
Learn reaction rates, the components of rate law and how to determine the rate law equation from a table and the reaction's elementary steps!
What Is a Rate Law? A rate law is a mathematical expression that relates the reaction rate to the concentrations of reactants. It is determined experimentally, not from the balanced chemical equation. For a general reaction A + B → C: rate = k [A]m[B]n.
This equation is a differential equation that relates the rate of change in a concentration to the concentration itself. Integration of this equation produces the corresponding integrated rate law, which relates the concentration to time.
Rate laws (sometimes called differential rate laws) or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants.
What is the Rate 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. For a reaction given by: aA + bB → cC + dD.
Consider the reaction between reactants A and B to form products C and D [1-5]. aA + bB → cC + dD. Where a, b, c, and d are the stoichiometric coefficients. The following expression gives the rate law. R = k [A] x [B] y.
