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.

Rates of chemical reactions are usually defined by comparing the change in reactant or product concentration over time. We could measure the rate at which N2 and H2 are consumed and the rate at which NH3 is produced. Due to the stoichiometry of the reaction, the rate of N2 use will be 1/3 the rate of H2 use, and 1⁄2 the rate of NH3 production.
Rate law is a mathematical relationship between the concentration of reactants in a chemical reaction and its rate. It can be used to calculate the reaction rate at a given temperature.
Consider the following rate expression, and then answer the following questions. The reaction 2 NO(g) + O2(g) 2 NO2(g) Obeys the following rate law: rate = k [NO]2 [O2]
Oct 27, 2022 · 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…
