Which outcome occurs when a PID controller in a chemical reactor achieves overshoot?

A)Increased reactant waste from oscillations

B)Decreased product purity from side reactions

C)Elevated energy consumption from instability

D)Accelerated catalyst degradation from hotspots✓

💡 Explanation

When a PID controller overshoots in a chemical reactor, the temperature or pressure exceeds the setpoint, because the controller corrects too aggressively, creating temporary hotspots. Therefore catalyst degradation is accelerated, rather than other listed effects that result from instability or consistent deviation.
