The rate law for this reaction is written as: rate = k[A]m[B]n rate = k [ A] m [ B] n. in which [ A] …
WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, … WebJan 25, 2024 · To make the different expressions for the rate to be equivalent, the rate expressions are divided by the stoichiometric coefficient present in the balanced chemical equation. Units of Rate of Reaction Concentrations of reactants and products are usually expressed in moles per liter, and time is usually expressed in seconds or minutes.
WebFeb 12, 2024 · Rate = k[A]s[B]t As you can see from Equation 2.5.5 above, the reaction rate is dependent on the concentration of the reactants as well as the rate constant. However, there are also other factors that can influence the rate of reaction. These factors include …
WebRate of formation of H 2 O H 2 O = 0.5 − 0 10 From the above calculations, we can see that rate at which H 2 is consumed is twice the rate at which O 2 is consumed. So, the stoichiometry of the reaction relates, rates of formation and disappearances of different reactants and products as follows.
