Cstr zero order reaction

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 WebJul 1, 2024 · The continuous stirred-tank reactor is known as CSTR, or commonly the stirred tank reactor (STR), and is similar to the batch reactor. ...
