Science

Which outcome dominates when a continuous stirred-tank reactor (CSTR) operates far above its designed heat transfer limitation under exothermic reaction?

A)Thermal runaway accelerates quickly
B)Equilibrium shifts favoring reactants
C)Reaction rate is consistently stable
D)Kinetic constant effectively diminishes

💡 Explanation

Thermal runaway occurs in a CSTR above heat transfer limits because the elevated temperature massively increases the reaction rate via the Arrhenius equation. Reaction rate accelerating leads to further heat generation; therefore runaway occurs rather than equilibrium, limited kinetic constant, or stable reaction rate.
