Zinc can be processed from its ore (sphalerite, ZnS) according to the following reaction. Using the data given, calculate Hrxn, in kJ/mol. 2 ZnS(s) + 3 O2(g) +2 C (s) 2 Zn(s) + 2 CO(g) + 2 SO2(g) Hrxn = ? Data: 2 ZnO(s) + 2 SO2(g) 2 ZnS(s) + 3 O2(g) Hrxn = 1084.24 kJ ZnO(s) + C(s) Zn(s) + CO(g) Hrxn kJ
