Carbon monoxide and hydrogen can react under different conditions to give different products. One system produces methyl alcohol, CH 3O H (g), when CO and H2 react in the presence of a suitable catalyst.

a. At 227°C, after the reaction has reached equilibrium, the partial pressures of CO, H 2, and CH 3O H are 0.702 atm, 1.75 atm, and 0.0134 atm, respectively. Calculate K c for the reaction at 227°C.

b. What is the K c for the decomposition of a half mole of CH 3O H to CO and H 2 at the same temperature?

c. Initially, a 10.00 L flask at 227°C contains only CH 3O H. After equilibrium is established, the partial pressure of CH 3O H is 0.0300 atm. What are the equilibrium partial pressures of hydrogen and carbon monoxide gases at that temperature?

d. Calculate the equilibrium constant for the original reaction at 50°C. (ΔH° f for CH 3O H (g) = -201.2 kj/mol)
