TNT explosions are very fast reactions involving the production of enormous quantities of heat and gaseous products. Thermodynamically, explosions are best described as:

Correct Answer: A. High entropy, exothermic reactions with a low activation energy.
TNT explosions are very fast reactions (the lower the activation energy the less a reaction is impeded) involving the production of enormous quantities of heat (exothermic) and gaseous products (the production of hot gases from a solid explosive dramatically increases the disorder of the system, thus high entropy).
