← ScienceWhich risk increases significantly as the reaction rate grows via autocatalysis?
A)Depletion of the starting reagents
B)Inhibition of the catalyst species
C)Uncontrolled thermal runaway condition✓
D)Increased selectivity for desired products
💡 Explanation
An exponential rate increase leads to a fast heat release because positive feedback in *autocatalysis* escalates, therefore thermal runaway is more likely, rather than catalyst poisoning or inherently better selectivity without other controls.
