WebJan 30, 2024 · The half-life of a first-order reaction is independent of the concentration of the reactants. This becomes evident when we rearrange the integrated rate law for a first-order reaction to produce the following equation: (1) ln [ A] 0 [ A] = k t Substituting [A] 0/2 for [A] and t1/2 for t (to indicate a half-life) into Equation 1 gives WebElemental analysis can be used to determine the amounts of substances in a mixture. For example, if elemental analysis tells us that a potassium supplement contains 22% K by mass, and we know that the K is present as KCl, we can calculate the grams of KCl in the supplement.
