 will be :  
  • a)
    –357 kJ
  • b)
    –731 kJ
  • c)
    –773 kJ
  • d)
    –229 kJ
Correct answer is option 'B'. Can you explain this answer?

The factor of ΔG values is important in metallurgy. The ΔG...
For the reaction 2ZnS → 2Zn + S2 ; ΔG1º = 293 kJ  ..........(1)
2Zn + O2 → ZnO ; ΔG2º = –480 kJ  ..........(2)
S2 + 2O2 → 2 SO2 ; ΔG3º = –544 kJ  .........(3)
ΔGº for the reaction 2ZnS + 3O2 → 2ZnO + 2SO2 can be obtained by adding eqn. (1), (2) and (3)
⇒ ΔGº = 293 – 480 – 544 = – 731 kJ
