For a multistep reaction the observed order of the reaction is generally determined by the 1. activation energy. 2. time at which the concentrations of all species are measured. 3. slowest reaction of the sequence. 4. stoichiometric coefficients of the net reaction. 5. ratio of reactant and product concentrations.
