Which risk increases disproportionately with an escalating exothermic reaction rate?

A)Loss of catalyst selectivity
B)Runaway reaction and overpressure
C)Decreased product separation efficiency
D)Reduced overall reaction equilibrium yield

💡 Explanation

Runaway reactions occur because the exothermic reaction generates heat faster than it can be dissipated; thermal positive feedback accelerates the reaction rate. Therefore, pressure increases rapidly, rather than the equilibrium shifting or catalyst being directly affected.
