← ScienceWhich outcome arises when reactor temperature exceeds safety constants?
A)Exothermic reaction rate increasingly accelerates.✓
B)Equilibrium shifts to favor reactants.
C)Endothermic reaction rate decelerates.
D)Inert gas production self-extinguishes reactions.
💡 Explanation
When reactor temperatures surpass control parameters, exothermic reactions accelerate due to the Arrhenius equation, because the increased kinetic energy overcomes the activation energy barrier; therefore, runaway reactions occur rather than self-limiting via equilibrium shifts.
