← ScienceWhich risk increases when an endothermic catalyst is starved?
A)Runaway auto-catalytic temperature excursions
B)Increased end-product yield rate
C)Decreased catalyst thermal expansion
D)Exothermic decomposition pathway activation✓
💡 Explanation
Exothermic decomposition becomes favored after catalysts are starved for reactants, which raises temperature; thermal equilibriums change because reactant consumption via the reaction lowers catalyst temperature therefore without reactants heat causes unintended reactions, rather than targeted pathways.
