Question: Use data from Table 7.2, together with the fact that r H = -3509 kJ mol -1 for the complete combustion of pentane, C

Use data from Table 7.2, together with the fact that ΔrH° = -3509 kJ mol-1 for the complete combustion of pentane, C5H12(l), to calculate ΔrH° for the reaction below.

5 CO(g) + 11 H(g) - C5H12(1) + 5 HO(1) A,H = ?

Table 7.2

TABLE 7.2 Some Standard Molar Enthalpies of Formation, AH at 298.15 K Substance CO(g) CO(g) CH4(g) CH(g)

5 CO(g) + 11 H(g) - C5H12(1) + 5 HO(1) A,H = ?
