Science

Which risk increases when the enthalpy change of reactants is similar to that of the products in a batch reactor?

A)Increased frequency factor variation
B)Reduced explosion severity
C)Thermal runaway susceptibility
D)Catalyst poisoning acceleration

💡 Explanation

Due to the small enthalpy change, a limited capacity exists to absorb increases in temperature from side reactions; therefore, thermal runaway risk arises rather than a less severe explosion, because uncontrolled rises accelerate reaction kinetics far beyond design assumptions.
