Question 12
For the reaction: CO2(g) + H2g)
CO(g) + H20(g)
2,0 mol of carbon diòxide and 1,0 mol of hydrogen
(gas) are sealed in a 2,0 dm° container and allowed
to reach equilibrium at 1 000°C. At this point the
amount of water vapour is 0,723 mol.
12.1 Calculate the value of the equilibrium constant
at this temperature.
12.2 An additional 0,277 mol of water vapour is
now pumped into the sealed 2,0 dm° container,
and the equilibrium is restored at 1 000°C.
12.2.1. How will the concentration of CO(g)
change? (Write only increases,
decreases or stays the same.)
12.2.2 Explain your answer to
Question 12.2.1 by making use of
Le Chatelier's principle.
12.3 The volume of the container containing the
equilibrium mixture is increased to 2,5 dm at
1 000°C.
12.3.1 Will the increases in volume have any
effect on the concentration of CO(g)?
Answer only YES or NO.
12.3.2 Explain the answer to Question 12.3.1.
