WebFor a first-order reaction, the half-life is given by: t1/2 = 0.693/k For a second-order reaction, the formula for the half-life of the reaction is: 1/k [R]0 Where, t 1/2 is the half-life of the reaction (unit: seconds) [R 0] is the initial reactant concentration (unit: mol.L -1 or M) WebMechanism 1. Mechanism 2. Remember that in simple cases, where the slow step is the first step of the mechanism, the orders tell you what is taking part in the slow step. In this case, the reaction is first order with respect to both A and B, so one molecule of each must be taking part in the slow step.

WebIn a first-order reaction, the half-life of the reactant is equal to ln (2)/k, where k is the rate constant of the reaction and ln (2) is the half-life of the product. It is critical to understand half-lives because they allow you to calculate when a …
