← ScienceWhich risk increases when a chemical plant's cooling system delays quenching an exothermic reaction?
A)Reduced catalyst surface area occurs
B)Uncontrolled chain branching accelerates✓
C)Equilibrium shifts towards reactants prevail
D)Product selectivity gets enhanced anyway
💡 Explanation
Delayed quenching of the reaction elevates temperature, thus uncontrolled chain branching accelerates because the high-temperature increases the concentrations of radical species, therefore this leads to a runaway reaction, rather than equilibrium shifting or catalyst malfunction.
