In the T2 Laboratories incident, was the runaway reaction endothermic or exothermic?

• A. Neither of the above
• B. Endothermic
• C. Unknown
• D. Exothermic

Answer: (D)

A runaway reaction is driven by rapid heat generation that overwhelms the ability to remove heat. This creates a positive feedback: as temperature climbs, the reaction goes faster, generating even more heat and raising temperature and pressure until containment fails. In the T2 Laboratories incident, the process released heat quickly and uncontrollably, leading to a dramatic rise in temperature and pressure and an explosion. If the reaction were endothermic, it would absorb heat rather than release it, so cooling would be the dominant concern rather than runaway heat buildup. Thus the event fits an exothermic runaway, not unknown or neither.
