Could these processes have occurred elsewhere in the solar system or are there conditions special to the hadean Earth that are needed?

The amount of CH4 seems to saturate after ~1000 hours. Does it mean that reaction reach equilibrium in the chamber or that Fe-oxides on the surface of Fe metal grain prevent further reaction?

Submitted by Aki Takigawa on Wednesday 24th June 14:59
Do you have comments on the amount of CH4 produced by impact events compared with the other sources of CH4?
