1.1. Define the term of standard enthalpy of combustion, ΔH^θ_c.

1.2. In ΔH^θ_c  state what is indicated by ^θ. 

1.3. Table 1 shows some values for standard enthalpy changes of formation that can be used to calculate the enthalpy change for the reaction between propane and oxygen.

Table 1

i) State the equation to calculate the enthalpy change for a reaction using enthalpy of formation data.

[1]  

ii) State the equation for the combustion of propane. 

[1]  

iii) Use the information in Table 1 and your answer to part i) and ii) to calculate the enthalpy change for the combustion of propane.

1.4. Table 1 shows some values for standard enthalpy changes of formation that can be used to calculate the enthalpy change for the formation of propan-1-ol. This is shown in the following equation.

3C (s) + 4H₂ (g) + ½O₂ (g) → CH₃CH₂CH₂OH (l) 

Table 2

Use the information in Table 2 to calculate the enthalpy change for the formation of propan-1-ol.
