Chemical Concepts Demonstrated: Complex stoichiometry, exothermicity
As the match travels down the tube, a massive flame and a loud roar shoot forth from the top of the tube.
Explanation (include important chemical equations):
The reaction witnessed involves a very complex stoichiometry:
5 CS2 + 10.8 NO -> 5.4 N2 + 2.6 CO + 2.4 CO2 +1.7 SO2 + 8.3 S
The reaction is first-order in CS2 and second-order in NO. The activation energy is 300 kJ/mol, which is the energy required to remove an S from CS2. The energy released in this reaction is a whopping 3,280 kJ/mol.
