Unfortunately, all the equations given in the reference www.petroleum.co.uk are wrong. Yes ! WRONG ! The person in charge of writing them does not know chemistry. Look ! I copy here the four first equations. They are all wrong ! 1) CH4 + 2 O2 --> 2 H2O + CO2 + CO ---> Wrong ! CO should be removed 2) CH4 + 2 O2 + N2 --> 2 H2O + CO2 + CO + NO ...

The equilibrium constant for the reaction $\ce{2H2 + O2 <=> 2H2O}$ is colossal, equal to $\mathrm{2.4 \times 10^{47}}$ at $\mathrm{500\ K}$ (source). This would ensure virtually 100% yield for the combustion of a stoichiometric mixture of oxygen and hydrogen in equilibrium conditions. However, a rocket engine is a reaction vessel that is far from ...
