WebFor a first-order reaction, it is given as, R = – d [A]/dt = k [A] Where, R is the reaction rate [A] is the concentration of the reactant A k is the rate constant The term d [A]/dt is the derivative of [A] with time. Units 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.
