The following reaction can be used to make H₂ for the synthesis of ammonia from the greenhouse gases carbon dioxide and methane:
CH₄(g)+CO₂(g)⇌2CO(g)+2H₂(g)
What is the percent yield of H2 when an equimolar mixture of CH₄ and CO₂ with a total pressure of 20.0 atm reaches equilibrium at 1200.K, at which Kp=2.626 x 10⁷
