WebJan 14, 2015 · Rate of disappearance is given as − Δ [ A] Δ t where A is a reactant. 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. WebThe rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity.
