← ScienceWhich consequence results when a chemical reactor exceeds threshold temperature?
A)Thermal runaway causes reactor explosion✓
B)Increased yield selectivity favours reagents
C)Catalyst deactivation boosts reaction
D)Endothermic reaction rate spontaneously diminishes
💡 Explanation
Thermal runaway results because an exothermic reaction's rate accelerates rapidly with temperature according to Arrhenius equation, therefore heat production overwhelms cooling, rather than stabilizing because endothermic reactions counteract increased kinetic energy.
