Differentiate elementary andnon-elementary reactions.?The reactions in which the rate equation corresponds to a stoichiometric equation arecalled elementary reaction.?The reactions in which there is no correspondence between stoichiometry and rateequation are known as Non-elementary reaction. and What are the various intermediates that can be formed in a non-elementary reaction?Free radicals, ions and polar substances, molecules, transition complexes are thevarious intermediates that can be formed ina non-elementary reaction
