Hydrogen and carbon dioxide gases are mixed at 800 K. A reversible reaction takes place. H₂(g) + CO₂(g) ⇌ H₂O(g) + CO(g) At equilibrium, the partial pressures of H₂ and CO₂ are both 10.0 kPa. Kp is 0.288 at 800 K. What is the partial pressure of CO in the equilibrium mixture?
A5.37 kPa
B18.6 kPa
C28.8 kPa
D347 kPa
