Multiple spectator ions are present when a precipitation reaction is this kind of reaction.
In bimolecular enzyme-catalyzed reactions of this type, the product of an enzyme with one substrate leaves before reaction with the second substrate. Neutralization reactions are most often of this type. Multiple spectator ions are present when a precipitation reaction is this kind of reaction. This reaction is most common with ionic compounds. For 10 points, name this type of reaction in which two compounds exchange ions or elements to form new compounds.
In bimolecular enzyme-catalyzed reactions of this type, the product of an enzyme with one substrate leaves before reaction with the second substrate.
