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

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
