Pseudo-first-order reaction

WebJul 12, 2024 · The half-lives of radioactive isotopes can be used to date objects. The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t 1/2 = 0.693/ k. WebIf m = 1, we say the reaction is pseudo-first-order and kobs is called a pseudo-first-order rate constant. For trial 1, flood the reaction mixture with a large excess of reactant B ( [B] …
