WebThe order of reaction is something that has to be determined experimentally and can't usually be obtained from the stoichiometric coefficients (x and y). Reactions are usually zero, first, second or third order, but can be anything, including fractional orders or even negative orders. WebA first order reaction depends on the concentration of only one reactant (a unimolecular reaction ). Other reactants can be present, but their concentration has no effect on the rate. The rate law for a first order reaction is Although not affecting the above math, the majority of first order reactions proceed via intermolecular collisions.
