Nitrogen (N2) - an overview | ScienceDirect Topics

The chemical equation is. (10.28) CH 4 + 1.667 ( O 2 + 3.76 N 2) → 0.333 CO 2 + 2 H 2 O + 0.667 CO + 6.267 N 2. The nitrogen (N 2) takes no part in this reaction and does not need to be considered. The energy liberated in the reaction ( Qp) is the difference between the enthalpies of formation of the products and reactants.
