Question:

Use standard enthalpies of formation from Table 7.2 and equation (7.22) to determine the standard enthalpy of reaction in the following reactions.

(a) C3H8(g) + H(g)  CH6(g) + CH4(g); (b) 2 HS(g) + 30(g) 2SO(g) + 2 HO(1).

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)

Eq. 7.22

A,H [cx AHc + dx AHD + ...]-[ax AHA + bx AHB +...] (7.22) weighted sum of A H values for the products
