Which consequence results when a packed-bed reactor's temperature fluctuates rapidly around the optimal value for a kinetically-controlled exothermic reaction?

💡 Explanation

Oscillations in product concentration emerge due to thermal runaway. Thermal runaway causes a rapid rate increase at temperature peaks, quickly consumed reactants; a subsequent rate decrease follows during troughs because Arrhenius equation dictates temperature sensitivity. Because of this, thermal runaway drives product concentration swings, rather than equilibrium constant shifts or catalyst life prolongation.
