What are the Challenges with Chain Reactions in Catalysis?
1. Control: Uncontrolled chain reactions can lead to runaway reactions, posing safety risks. 2. Deactivation: Catalysts can become deactivated over time due to poisoning or fouling, which can halt the chain reaction. 3. Side Reactions: Unwanted side reactions can occur, leading to by-products that may need to be separated from the desired products.
