Multiple steady states are known to exist in nonisothermal nonadiabatic systems for a certain range of parameter values. It has been elucidated that in a certain region of Damkohler numbers five steady states classified as kinetic, diffusion and intermediate regimes are possible. The results of the effects of the external fluctuations on the system behaviour are reported in this article. A nonisothermal nonadiabatic tubular reactor was analyzed in the presence of external disturbances. The study, while not revealing any noise induced transitions, clearly shows the preference of evolving states in the presence of noise.
