← ScienceWhich consequence results should a batch reactor experience unexpected auto-catalysis?
A)Lower activation energy threshold attained
B)Exothermic reaction runaway accelerates quickly✓
C)Equilibrium constant becomes easily reversible
D)Reaction order shifts towards first order
💡 Explanation
Thermal runaway accelerates reaction rates because positive feedback via autocatalysis amplifies exothermic heat. Therefore temperature rises rapidly rather than achieving threshold changes or shifting the order, because auto-catalysis overwhelms normal cooling.
