A CSTR has one feed stream F1, and one exit stream, F2. The feed contains pure species A, which undergoes a second order reaction in side the reactor. The term for the reaction of species A in the reactor, in the differential equation that describes the change in concentration of A, dtdCA, is best represented by: F1CA,1CA2k0eRTEaCA2k0eRTEaF2CA,2CAk0eRTEaCAk0eRTEaF1CA,1F2CA,2 A CSTR has one feed stream F1, and one exit stream, F2.
