Cstr modelling 1st order reaction
Webbe simplified to a general nth-order reaction. r A = k n [A]n where n ≅2. With good experimental data, this model allows the determination of the reaction order for an irreversible reaction. The effect of temperature on the rate constant can be compared with that predicted by the WebTypical examples of reaction rates are a first order reaction given by, r A= kC A (1.2.4) or a second order reaction, 2r A= kC A (1.2.5) where kis called the rate constant, Usually the order of the reaction provides some insight into the molecular mechanism for the reaction. A first order reaction corresponds to a uni-molecular process, whereas a
