In methane conversion to hydrogen devices, there are two possible reactions in the converter: CH4+2H2O—CO2+4H2 and CH4+H2O—CO+3H2. Please discuss which of these reactions should be considered valid during the conversion process.
Which one to prioritize is not a matter of accuracy; change the word \"accuracy\" above to \"priority\"

In other words, the conversion reaction proceeds as follows: Step 1: Methane reacts with water to produce hydrogen and carbon monoxide: CH4+H2O→CO+H2. Step 2: Part of the carbon monoxide produced then reacts further with water to yield hydrogen and carbon dioxide: CO+H2O→CO2+H2
Both have them; generally, it’s hard to determine which is primary or secondary based on the components of the converted gas. It’s possible that some of the CO is not fully converted and goes on to be converted into CO2 in the medium-temperature shift reactor
The conversion reaction is a very complex one, with multiple reactions occurring simultaneously; it can be said that there are many of them
The conversion reaction involves multiple reactions occurring simultaneously – with different operating conditions – resulting in varying amounts of products
