Which outcome occurs when the temperature-control feedback response increasingly oscillates around the setpoint in a chemical reactor?

A)Equilibrium shifts cyclically with damped oscillations
B)Runaway reaction quenches after a peak
C)Catalyst deactivation accelerates exponentially
D)The reaction reaches steady state rapidly

💡 Explanation

The temperature fluctuating around setpoint indicates imperfect control negatively impacting the reaction equilibrium, leading to oscillations via Le Chatelier's principle driving the equilibrium back and forth. Therefore, 'equilibrium shifts cyclically' is accurate rather than simple deactivation, which will change the parameters rather than oscillatory equilibrium itself.
