A mixture of 0.02829 mol of CH₄, 0.02775 mol of H₂S, 0.04335 mol of CS₂, and 0.04158 mol of H₂ is placed in a 1.0-L steel pressure vessel at 2484 K. The following equilibrium is established:

1 CH₄(g) + 2 H₂S(g) 1 CS₂(g) + 4 H₂(g)

At equilibrium 0.01750 mol of H₂S is found in the reaction mixture. (a) Calculate the equilibrium partial pressures of CH₄, H₂S, CS₂, and H₂. P_eq(CH₄) = . P_eq(H₂S) = . P_eq(CS₂) = . P_eq(H₂) = . (b) Calculate K_P for this reaction. K_P = .
