reason for omitting 8.55

Are we omitting problem 8.55 because the O2 does not cancel out and there still remains (1/2) O2(g)?

It is omitted because the second reaction isn't balanced and so it is unclear what the enthalpy really refers to.


Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
