Which outcome arises when a packed bed reactor designed for continuous exothermic reaction exceeds optimal heat transfer?

💡 Explanation

Thermal runaway occurs because positive feedback of reaction rate on temperature overcomes heat removal; therefore, temperature escalates causing thermal explosion, rather than the rate simply accelerating since heat transfer cannot balance heat generated.
