Web13. For a certain reaction that follows second order kinetics, A + B C+DEE the value of the rate constant, k, was measured at several different temperatures and the ... WebThat means that that particular term disappears from the rate equation. The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2. We call this an overall second order reaction.
WebFor a second-order rate constant, such as kin Eqn (6), the units are dm3mol-1s-1or L mol-1s-1or M-1s-1. The concept of order of reaction (but not molecularity) can also be applied to certain reactions that occur by composite mechanisms, provided that the rate is proportional to reactant concentrations raised to powers (which need not be integral).
