← ScienceWhich risk increases when a chemical reactor operates significantly off ideal equilibrium constant conditions?
A)Runaway reaction from accelerated kinetics✓
B)Catalyst poisoning from byproduct formation
C)Reduced yield due to competing pathways
D)Increased energy consumption for maintaining stability
💡 Explanation
When reactants are far from the concentrations predicted by the equilibrium constant, the reaction shifts to restore equilibrium, causing the faster kinetics and heat generation, driving a positive feedback loop and increasing risk of a runaway reaction. Therefore, a runaway reaction is more likely, rather than catalyst poisoning, reduced yield or increased energy solely which require different mechanisms.
