← ScienceWhich outcome occurs when exceeding the temperature limit of an endothermic reaction cycle?
A)Runaway reaction accelerates exponentially✓
B)Catalyst degrades reducing reaction rate
C)Equilibrium shifts producing more reactants
D)Refrigeration load decreases significantly
💡 Explanation
A runaway reaction occurs because above the temperature limit, positive feedback overwhelms the reaction's control loop; therefore, the reaction accelerates producing higher temperatures rather than achieving equilibrium or catalyst degradation under normal conditions.
