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. WebNope, we are assuming it is a first order reaction because this reaction only has one step. And this step only has one reactant with a coefficient of 1. If this reaction has multiple steps, even if it has one reactant, the order of reaction may not necessarily be equal to 1.
