Problem: Use bond energies to predict ΔE for the following reaction:H2S(g) + 3F2 (g) → SF4 (g) + 2HF(g)

FREE Expert Solution

E = Ebond, reactant - Ebond, product


Reactant:

2 S-H bond: 347 kJ x 2 = 694 kJ

3 F-F bond: 154 kJ x 3 = 462 kJ

                             Total = 1156 kJ


Product:

4 S-F bond: 327 kJ x 4 = 1308 kJ

2 H-F bond: 565 kJ x 2 = 1130 kJ

                             Total = 2438 kJ
