The determination of rate law from experimental data is one of the most important parts of chemical kinetics. The methods used in textbooks and literatures are linear fitting methods of reactant concentration or pressure, most of which are with heavy workload. Many reactions are studied by measuring the physical properties of the system instead of reactant concentration, but there is no universal method to determine rate law from physical properties. Here a universal method for determining rate law from curve fitting of physical properties or reactant concentration is presented, both the reaction order and rate constant are obtained at the same time. The good fitting results for reactions of all kinds of orders are obtained. This method is of great significance for chemical kinetics.
