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. WebFor a first-order reaction in a CSTR, compare the predicted performance for completely segregated flow with that for nonsegregated flow. From Example 14-4, we conclude that the performance for a first-order …
