Hey can someone help me with the following extension questions from pag 3.3- Determination of an enthalpy change of combustion-
1) Work out the difference between the enthalpy values for each successive member of the alcohol homologous series. WHY IS THE DIFFERENCE A CONSTANT VALUE?
2)PREDICT A VALUE FOR THE ENTHALPY CHANGE OF COMBUSTION OF DODECAN-1-OL
3) WHY ARE THESE CALCULATIONS NOT STANDARD ENTHALPY CHANGES?

2) should follow from 1)
3) did you do the experiment under standard conditions?
