Reaction in an Isothermal Continuous Stirred-Tank Reactor (CSTR)

WebFeb 12, 2024 · If the number of enzyme molecules is limited in relation to substrate molecules, then the reaction may appear to be zero-order. This is most often seen when two or more reactants are involved. Thus if the reaction (1) A + B → products is first-order in both reactants so that (2) rate = k [ A] [ B] WebIn first-order reactions in which the rate-limiting step is the protonation of the reactant, the sorption of the reactant dominates the rates. Identical intrinsic rates of reactions were observed for the cracking of alkanes over zeolites of different structure types and after post-synthesis treatments.
