Question: Use the information given here, data from Appendix D, and equation (7.22) to calculate the standard enthalpy of formation per mole of ZnS(s). Eq.7.22 2

Use the information given here, data from Appendix D, and equation (7.22) to calculate the standard enthalpy of formation per mole of ZnS(s).

2 ZnS(s) + 3O(g) 2 ZnO(s) + 2 SO(g) A,H -878.2 kJ mol-1

Eq.7.22

A.H = [cx AHC + dx AHD +...] [ax AHA + bx AHB + .] (7.22) weighted sum of AcH values for the products

2 ZnS(s) + 3O(g) 2 ZnO(s) + 2 SO(g) A,H -878.2 kJ mol-1
