First-order reaction
WebFirst-Order Reactions. We can derive an equation for determining the half-life of a first-order reaction from the alternate form of the integrated rate law as follows: If we set the time t equal to the half-life, , the corresponding concentration of A at this time is equal to one-half of its initial concentration (i.e. : WebJul 5, 2024 · The first-order reaction is defined as the chemical reaction in which the rate of reaction is linearly dependent on the concentration of only one reactant and this is the …

WebHalf-Life Formula. It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1/2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1/2 = 0.693/k. WebA first-order reaction depends on the concentration of only one reactant. As such, a first-order reaction is sometimes referred to as a unimolecular reaction. While other reactants can be present, each will be zero-order, since the concentrations of …
