The following elementary, liquid-phase reaction is carried out in a CSTR with a heat exchanger: A ↔ B

Should the operators be concerned of a possible runaway reaction if the reactant feed was suddenly shutoff while operating at a steady-state temperature of 393.7 K? Assume the feed consists of pure A, neglect any shaft work, the volume of the liquid does not change, the coolant mass flow rate is very high, and the conversion X = 0.457 at the time the feed was shutoff.

Additional information:

k = 1.0 min-1 at 375 K
E = 40,000 cal/mol
KC = 100 at 375 K
ΔHRxo = – 75,000 cal/mol
NAo = 100 mol
Ta = 310 K
UA = 3,700 cal/min/K
CPA = CPB = 40 cal/mol/K
