If the reaction is second order, then two units of concentration are already present so the rate constant needs reciprocal time plus inverse units of concentration, L mol ( ^{-1} s^{-1} ). If the reaction is third order, the rate constant should have units of ( L^{2} mathrm{mol}^{-2} mathrm{s}^{-1} ).
