WebThe Haber process usually uses metal catalysts to help the bonds break. It runs at extremely high temperatures and pressures, enough to cause worry that it will burst steel vessels. At these conditions breaking $\ce{N2}$ and $\ce{H2}$ can and does happen. It's true that the nitrogen-nitrogen bond is broken, but once that happens ammonia forms ... WebCN2 = 0.78 mol/mol; N2 accounts for 78% of all molecules in the atmosphere. Next in abundance are molecular oxygen (O2) with CO2 = 0.21 mol/mol, and argon (Ar) with CAr = 0.0093 mol/mol. The mixing ratios in Table 1-1 are for dry air, excluding water vapor. Water vapor mixing ratios in the atmosphere are highly variable (10-6-10-2 mol/mol ...
