✦ Synopsis

New and very strong cntena are presented for a pnon predIctIon of the condltlons for which the steady-state lumped parameter model of an nth order chenucal reaction (n = 0) m an adiabatic CSTR has txther a umque or multiple solutions The cntena show that the higher the order of the reaction the smaller IS the region m the parameters space for whch multiphclty can occur New umqueness and multiphcclty cnterla are developed also for an n th order reaction m a porous catalyst usmg a model, wluch accounts for rntraparhcle concentration gradients, whale assurnmg a undorm mtrapartlcle temperature dxfferent from the ambient one The region m the parameters space for whch steady state multrpllclty can occur for tlus model IS smaller than that for a correspondmg lumped model, which mores the mtrapartlcle concentration gradients
