Hydrogen for industrial processes and fuel cells is obtained from hydrocarbons. C_3H_8(g) + 3 H_2O(g) reversiblearrow 3 CO(g) + 7 H_2(g) K_P(900 K) = 1.5 middot 10^6 bar^6 CO(g) + H_2O(g) reversiblearrow CO_2(g) + H_2(g) K_P(900 K) = 1.6 Determine the equilibrium constant for the overall reaction. C_3H_8(g) + 6 H_2O(g) reversiblearrow 3 CO_2(g) + 10 H_2(g) (Answer: K_P = 6.14 middot 10^6 bar^6) From an initial propane pressure of 25 bar and water vapour pressure of 80 bar in a sealed reactor, determine the partial pressure of hydrogen at 900 K. (Answer: P_H_2 = 36.2 bar)
