Greatest rate of disappearance
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.
