WebA reaction rate can have a negative partial order with respect to a substance. For example, the conversion of ozone (O 3) to oxygen follows the rate equation in an excess of oxygen. This corresponds to second order in ozone and order (−1) with respect to oxygen. [29] WebJan 14, 2015 · However, using this formula, the rate of disappearance cannot be negative. Δ [ A] will be negative, as [ A] will be lower at a later time, since it is being used up in the reaction. Then, [ A] final − [ A] initial will be negative. Therefore, the numerator in − Δ [ A] Δ t will be negative.
