← ScienceWhich risk increases when equilibrium constant increases significantly for exothermic reversible reaction?
A)Runaway reaction due to rapid heat✓
B)Catalyst poisoning by side products
C)Reverse reaction dominates products
D)Reduced yield limited by Le Chatelier
💡 Explanation
When the equilibrium constant of an exothermic reversible reaction increases greatly, heat production accelerates because the forward reaction is strongly favored, potentially leading to a thermal runaway situation. Therefore runaway reaction results, rather than catalyst poisoning, reverse dominance, or low yield, each require other unfavorable thermodynamic or kinetic conditions.
