So where is Venus's oxygen? It has more than enough CO2 to make oxygen from abiotically, and the higher surface temperatures should be expected to aid the process.
This is fascinating and I'd like to know more about what is going on here, but chemistry isn't really my forte so I'm kind of reliant on interpreting what I read on Wikipedia at face value. From wiki page on Venusian atmosphere, I'm seeing that oxygen is getting drawn into the sulphuric acid cycle in the atmosphere. Would this explain where the oxygen is going?
I think this is a possible explanation. There could be an equilibrium between sulphur dioxide and sulphuric acid that takes up atmospheric oxygen.
