← ScienceWhich risk increases when a packed-bed reactor’s inlet temperature spirals uncontrolled?
A)Selectivity favors undesired products✓
B)Catalyst attrition rate decreases notably
C)Equilibrium shifts exothermically towards reactants
D)Pressure drop across bed stabilizes
💡 Explanation
When temperature spirals, thermal runaway shifts selectivity towards side reactions because complex kinetics are more sensitive; therefore, byproduct formation accelerates rather than the equilibrium driving reversibility. This happens due to Arrhenius equation dominance in some thermal decomposition pathways.
