Question:

Use Table 9.4 to calculate an approximate enthalpy of reaction forCH4(g) + 202(g)  CO(g) + 2HO(g)

Table 9.4TABLE 9.4 Bond Energies (kJ/mol)* Single Bonds C-H C-C C-N C-O C-F C-C1 C-Br C-I C-S Si-H Si-Si Si-C Si-O 414

Strategy

Use Equation 9.2, being careful to substitute the correct number of moles of bonds being formed or broken. Also, write the Lewis structure of each species to determine the types (single, double, or triple) of bonds being formed or broken.

Equation 9.2AHreaction = (moles of bonds broken X bond energies of bonds broken) - (moles of bonds formed X bond energies
