← ScienceWhich risk increases when a chemical reactor nears runaway?
A)Decreased production catalyst surface area
B)Excessive exothermic reaction accelerant rate✓
C)Reduced internal temperature gradient control
D)Increased input fluid mixing intensity
💡 Explanation
An accelerant drives higher reaction rate output, resulting in rapid temperature increase because thermal runaway is caused by autocatalysis. Thus the reaction rate increases faster, therefore accelerating and risking explosion rather than temperature control easing.
