Hydrogen and carbon dioxide gases are mixed in equal molar amounts at 800K. 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 800K. What is the partial pressure of CO in the equilibrium mixture?
A5.37 kPa
B18.6 kPa
C28.8 kPa
D347 kPa
