Tīmeklis2024. gada 12. apr. · The rate law expression for the reaction was rate=k [FeCl 3] 1 [KI] 0, which was equivalent to rate=k [FeCl3] 1. Calculating rate constant from the data was possible because the order of the reaction and the concentrations of the reactants were known. The rate constant was calculated by substituting the rate of one of the runs …
