A mixture of 0.02916 mol of H₂O, 0.09900 mol of CH₄, 0.02040 mol of CO, and 0.09624 mol of H₂ is placed in a 1.0-L steel pressure vessel at 1015 K. The following equilibrium is established:

1 H₂O(g) + 1 CH₄(g) 1 CO(g) + 3 H₂(g)

At equilibrium 0.009660 mol of CO is found in the reaction mixture. (a) Calculate the equilibrium partial pressures of H₂O, CH₄, CO, and H₂.

(b) Calculate K_P for this reaction.
