1. Define reaction enthalpy.
2. Define standard enthalpy.
3. The standard heat of formation of Fe2O3 (s) is 824.2kJ mol-1 Calculate heat change for the reaction.
4Fe(s) + 302 (g) →2Fe2O3(s)
4. Calculate the heat of combustion of ethylene (gas) to from CO2 (gas) and H2O (gas) at 298k and 1 atmospheric pressure. The heats of formation of CO2, H2O and C2H4 are – 393.7, - 241.8, + 52.3 kJ per mole respectively.
5. Give two examples of reactions which are driven by enthalpy change.
6. Will the heat released in the following two reactions be equal? Give reasons in support of your answer.
(i) H2 (g) + ½ O 2 (g)→H2 O (g)
(ii) H2 (g)+ ½ O2 (g) →H 2O (l)
7. What is the relation between the enthalpy of reaction and bond enthalpy?
8. The reaction C (graphite) + O2 (g) →CO2(g) + 393.5 kJ mol-1 represents the formation of CO2 and also combustion of carbon. Write the DHO values of the two processes.
