Pls help ASAP. 

Given the following data:
H2S(g) + 3/2O2(g) → H2O (1) + SO2(g)
1/8 Sg(s) + O2(g) → SO2(g)
H2(g) + 1/2O2 → H2O (1)
->
Compute ArHº for H2(g) + 1/8 S8 (s) → H2S(g) in kJ/mol.
-
a) 265.3 kJ/mol
Ob) 562.3 kJ/mol
Oc) -1.6 kJ/mol
O d) 276.6 kJ/mol
e) 20.5 kJ/mol
ArH=-562.3 kJ/mol
ArH=-297.0 kJ/mol
ArH=-266.9 kJ/mol
