equilibrium in terms of pressure

Hi guys,
I hope someone can help me here. I need an explanation for this graph. I came up with one but i am not confident at all with it.

'

𝐶 + 2𝐻₂𝑂 ↔ 𝐶𝑂2 + 2𝐻2 [reaction 1(1.6)] 𝐶+𝐻2𝑂 ↔𝐶𝑂+2𝐻2 [reaction 2 (1.7)]
𝐶 + 2𝐻2 ↔ 𝐶𝐻4 [reaction 2(1.8)]

The graph above shows how the mole fractionis affected at different pressures with increasing temperature. Le chatelier’sprinciple is used to counteract the changes to the conditions, which is caused bythe different pressures. Pressure occurs due to molecules hitting the walls oftheir container. The more molecules there are, the higher the pressure will be.The system reacts in a way so the amount of molecules produced is less. In thiscase, it can be confirmed that in both reactions 1 and 2 the equilibrium shiftsto the right hand side producing more products, whilst the reverse happens inreaction 3

please help. thanks
