Perturbations around steady states of a system of cerium or manganese bromide and bromate ions in a sulfuric acid solution, in a continuous stirred tank reactor (CSTR), are investigated. Two kinds of perturbations are discussed, namely, small-species and large-constraint ones. The feasibility of measuring a particular rate constant by following the system behavior after a small perturbation is analyzed. Some general theorems regarding this behavior are obtained. Large perturbations, namely, those that cause a transition of the system from one steady state to another, are analyzed and an approximate relationship between the perturbations' intensity and length is developed. The results are in good agreement with the experimental data.
