The video tutorial revisits integrated rate laws for first and second-order reactions, using experimental data to determine the reaction mechanism. By calculating rates with given rate constants and comparing them to the observed rate, the video concludes that the reaction is likely first-order. It emphasizes that mechanisms can only be disproven or shown to fit data, not proven with certainty.
