Method of initial rates definition chemistry

WebExperimental Use of the Initial Rates Method When Only One Reactant is Present. The method of initial rates can be used experimentally by running a reaction, such as A → product, with different starting concentrations of A and measuring how the concentration of A decreases over time. The resulting data can be plotted as seen in Figure 1 ... WebThe method of initial rates looks at how the initial rate of a reaction changes when the initial concentration of the reactants are also changed, one reactant at a time. Once the orders of the reaction are known, the rate constant can also be calculated. Key Equations rate = k [A] m [B] n Glossary method of initial rates
