Use bond-dissociation enthalpies (Table 4-2, p. 143) to calculate values of for the following reactions.
Solution 40SP:
Here, we are going to calculate the bond enthalpy change for each of the reaction.
Step 1:
The overall enthalpy change for a reaction is the sum of the dissociation enthalpies
of the bonds broken minus the sum of the dissociation enthalpies of the bonds formed.
o = [Bond dissociation energy for bonds broken] -[Bond dissociation energy for bonds formed]
