🤓 Based on our data, we think this question is relevant for Professor Pelton's class at UMN.
Calculate ΔH°rxn for the reaction
2Ni (s) + 2S (s) + 3O2 (g) → 2NiSO3 (s)
from the following information:
(1) NiSO3 (s) → NiO (s) + SO3 (g) ΔH°rxn = 156 kJ
(2) S (s) + O2 (g) → SO2 (g) ΔH°rxn = - 297 kJ
(3) Ni (s) + 1/2O2 (g) → NiO (s) ΔH°rxn = -241 kJ
