8.3 Kinetics of Enzyme-Catalyzed Reaction The Rate Law of Unimolecular reactions(review) Consider a reaction ofoverall stoichiometry, A->P The rate,or velocity,v of this reaction is the amount of P formed or the amount of A consumed per unit time.Thus: V= d[P] d[A] Or V= dt dt Rate law states that: v=- (=kA] dt Where k is rate constant.v is a function of [A]to the first power,or the first order.k is called first order constant. 8.3 Kinetics of Enzyme-Catalyzed Reaction The Rate Law of Unimolecular reactions (review) • Consider a reaction of overall stoichiometry, The rate, or velocity, v of this reaction is the amount of P formed or the amount of A consumed per unit time. Thus: Rate law states that: Where k is rate constant. v is a function of [A] to the first power, or the first order. k is called first order constant. dt d A or v dt d P v [ ] [ ] = = − A→ P [ ] [ ] k A dt d A v = − =
