How to determine rate constant from data
WebAug 9, 2024 · rate = k [ NO] 2 [ H 2] The sum of the exponents is 2 + 1 = 3, making the reaction third-order overall. Once the rate law for a reaction is determined, the specific rate constant can be found by substituting the data for any of the experiments into the rate law … WebJun 19, 2024 · t 1/2 =. k=. If we know the value of the initial concentration of reactants and half-life then we can calculate the rate constant for the zero-order reaction. The half-life for a first-order reaction is. t 1/2 =ln2/k. k=ln2/t 1/2. If the value of half-life is known then we can calculate the rate constant.
