Which risk increases in an industrial reactor when the available heat is significantly removed during an exothermic reaction?

A)Catalyst surface area decrease
B)Thermal runaway suppression
C)Refrigerant pump failure
D)Reduced activation energy

💡 Explanation

Thermal runaway suppression occurs due to insufficient heat dissipation; reaction rates accelerate following Arrhenius equation behaviour releasing further heat in positive feedback because heat cannot be removed sufficiently; therefore a dangerous temperature spike risk increases rather than thermal equilibrium which would decrease reaction rate.
