Question from OCR A Student Book: 9.3 Summary Questions

Use Table 1 and the following data:

2SO2(g) + O2(g) → 2SO3(g) ΔH= -192kJmol-1

Assume that SO2 and SO3 contain only S=O bonds
a) Calculate the average bond enthalpy for the S=O bond.
b) The actual bond enthalpy for the S=O bond in SO2 is 531kJmol-1. Calculate the actual bond enthalpy for the S=O bond in SO3.

For a) 345
for b) 469
Is this correct?
