What is a potential risk of a reaction rate that is too high?

A reaction rate that is excessively high can lead to a risk of explosion due to the rapid generation of gas or heat, which can create dangerous pressure build-ups in a closed system. When reactions proceed at high rates, the energy released can lead to thermal runaway situations where the temperature continues to rise, further accelerating the reaction and increasing the likelihood of an explosive event. This is particularly critical in reactions involving volatile substances or where large quantities of gas are produced.

While other factors like the formation of unwanted by-products can occur, they are generally not as immediate or hazardous as the risk of explosion associated with high reaction rates. Managing reaction rates is essential for ensuring safety in chemical processes, especially in industrial settings where large scale reactions take place.
