5. Passing steam over hot carbon produces a mixture of CO and H₂, also known as the water gas reaction. H₂O(g) + C (s) CO (g) + H₂ (g) The value of Kc for the reaction at 1000 °C is 0.032. Calculate the equilibrium partial pressures of the products and reactants at 1000 C if PH₂0 = 0.442 atm and Pco = 5.0 atm at the start of the reaction. Assume carbon is in excess. (note: convert Kc to Kp, or assume a volume and convert pressures to concentrations)

5. Passing steam over hot carbon produces a mixture of CO and H₂, also known as the water gas
reaction.
H₂O (g) + C (s) CO (g) + H₂ (g)
The value of Kc for the reaction at 1000 °C is 0.032.
Calculate the equilibrium partial pressures of the products and reactants at 1000 C if PH₂0 =
0.442 atm and Pco = 5.0 atm at the start of the reaction. Assume carbon is in excess. (note:
convert Kc to Kp, or assume a volume and convert pressures to concentrations)
