Question

Water Gas The water-gas reaction is a source of hydrogen. Passing steam over hot carbon produces a mixture of carbon monoxide and hydrogen: CO(g) H The value of Kc for the reaction at 1000°C is 3.00 x10 2. a. Calculate the equilibrium partial pressures of the products and reactants if PH20 *0.442 atm and Poo 5.000 atm at the start of the reaction. Assume that the carbon is in excess. Number Number PH, 0.167 0.275 H,O atm atm Be careful about rounding your answers in intermediate Number steps. You should only round the final answer. 5.167 CO atm b. Determine the equilibrium partial pressures of H20, CO, and H2 after CO and H2 at 0.075 atm are added to the equilibrium mixture in part a. Number Number atm P., 0.047402 atm PH 0.32683 Number 5.1972 CO atm

Explanation / Answer

Kc = Kpdn

3*10-2 = Kp1 = Kp = 0.32683/5.1972[PH2] = >

PH2 = 0.32683/5.1972*3*10-2 = 2.096 atm
