9. Given the overall reaction from the previous problem
2 CO (g) +6 H2 (g) =2 CH4 (g) + 2 H20 (g)
Using Le Chatelier's principle, predict which direction the reaction will shift to
reestablish equilibrium for each of the following changes:
A. Carbon monoxide is increased. [-3 points]
B. Methane is decreased. [-3 points]
c. The reaction is placed in a dehydration chamber (which siphons off water). [-3
points]
D. If the pressure in the reaction container is doubled. [-3 points]
E. Calculate the enthalpy of reaction for this reaction using the standard
thermodynamics values for the reactants and products. Is the reaction
endothermic or exothermic?
F. Now, use Le Chatelier's principle again to determine the direction the
equilibrium will shift if heat is added to the reaction. [-3 points]
G. If 35 kPa of CO is mixed with 35 kPa of hydrogen in a 1.5L container at 25°C,
what is the theoretical yield of methane?
