2) Propanone is a liquid. It has the structure
H O H
l ll l
H- C - C - C -H
l l
H H
The equation for the complete combustion of propanone is:
CH3COCH3(l) + 4O2(g) 3CO2(g) + 3H2O(l)
a) Use the following bond energies (in kJ mol–1) to calculate a value for the standard enthalpy change of
this reaction:
E(C C) = +347
E(C H) = +413
E(O O) = +496
E(C O) = +805
E(O H) = +465 [4]
