Homework Help: Chemistry

One proposed design for a Mars rover uses a methane gas fuel cell as its power supply. The methane fuel can be made on Mars using a chemical reaction that has been known for over 100-a the Sabatier methanation reaction:
C02(g) + 4H2(g)<--> CH4(g) +2H2O(g)
Enthalpy change is -165 KJ at 250 degrees celsius.

Predict, using Le Chatelier's Principle, the conditions required in a closed Sabatier reactor to produce the maximum amount of methane.
