← ScienceWhich risk increases in exothermic industrial reactors lacking precise thermal management?
A)Runaway reaction rate escalates rapidly✓
B)Catalyst deactivation reduces yield slowly
C)Equilibrium shifts toward reactants subtly
D)Thermal gradients induce phase separation
💡 Explanation
Uncontrolled heat accumulation leads to accelerating reactions, because "thermal runaway" is exponentially dependent on temperature via the Arrhenius Equation’s rate constant; therefore the reaction rate increases sharply, rather than a gradual shift toward reactant equilibrium.
