A mixture consisting of 0.2000 mol CO2, 0.1000 mol Hz and 0.1600 mol H20 is placed in a 2.00-L vessel. The following equilibrium is established: CO:(9) + H2(9) CO(9) + H20(9) At equilibrium, [H;O] = 0.0856 M. a) What are the equilibrium concentrations of CO2, Hz and CO? b) Calculate K- for the reaction.

9 Methanol is produced synthetically: CO (g) + 2H2 (g) CH;OH (g) A H=+24 Kcal a) Write the Equilibrium Constant Expression: b) Is it an Endothermic or Exothermic Reaction? c). Indicate the effect on the equilibrium, ie., does the reaction shift to the right, to the left, or have no effect on the reaction at all: 1. Increase in [2H2] = 2. Decrease in [CO] = 3. Increase in Temperature = 4. Increasc in Pressure = 5. Addition of a catalyst =,
