✦ Synopsis

Exact multlphclty and umqueness cnterla for steady state m a non-adiabatic contmuous stirred tank reactor are studled through simple tangent analysis for binary, exothermlc reactlon of the type A + bB -Products with rate expresslon zA = EGC",, where A IS the hmitmg reactant Important parameters for multlpllclty crltena are reactlon orders m and n, stolchlometnc coeffiuent b, the ratlo p of feed concentration of A to that of B, dunensionless actlvatlon energy Q, dlmenslonless heat of reactlon 8, dunenslonless heat transfer coefficient y and dlmenslonless coolant temperature $ Necessary condrtlons for the system to have multiple exit conversions (temperatures) are defined m the (m, n, b, p, a,fl, y, I&) space Multtphclty 1s guaranteed by lunitmg the dimensIonless space time 13 m a proper range m addltlon to the necessary condltlons Effects of various parameters on multlphclty and uniqueness are numencally calculated and graphically represented Theoretical predrctzon for multlpllaty are further compared with mulbphclty data reported m literatures
