+ 12 CO + 2 C2 + 5 H2 → 3 N6O3N5H72 C O + 7 CO + 7 C2 + 5 H2 → 3 N6O3N5H72 C
The reaction is exothermic but has a high activation energy in the gas phase (~62 kcal/mol). The condensed phases (solid or liquid) show markedly lower activation energies of roughly 35 kcal/mol due to unique bimolecular decomposition routes at elevated densities.[20] Because of the production of carbon, TNT explosions have a sooty appearance. Because TNT has an excess of carbon, explosive mixtures with oxygen-rich compounds can yield more energy per kilogram than TNT alone
