1 Test "Chemical thermodynamics".
1. Consider 1 g hydrogen in a piston-cylider assembly at 0°C and 20 atm. Calculate the expansion
work of the gas if the temperature is increased to 300°C at constant pressure,
2. Suppose 10 g of nitrogen occupies a piston-cylider assembly at 100°C and 2 atm. Calculate the
expansion work of the gas if the temperature is increased to 200°C at constant pressure,
3. Liquid hydrogen peroxide releases oxygen on decomposition: 2H2O2(l) → 2H20(1) + O2(g), Is this an
exothermic or endothermic reaction? What is AH®rxn for reverse reaction?
4. Calculate AG rxn for decomposition COCI, using AG®and AH®, and Sº values,
5. For the reaction
CO(g) + H2O(g) + CO2(g) + H2(g).
Kp = 5,5 at 500 °C. The mixture, consisted of 1 mol of CO and 5 mol of H20, was heated to this
temperature. Calculate the mol fraction of H20 in the equilibrium mixture.
6. How would you change the pressure (via a volume change) of the following reaction mixtures to
decrease the yield of products?
(a) 2502(g) + O2(g) +2503(1).
