Hydrogen Peroxide Is a Good Oxidizing Agent Because It Is $\rightarrow$

Hydrogen peroxide is a good oxidizing agent because it is a good source of molecular oxygen: 2 H₂O₂(aq) $\rightarrow$ 2 H₂O(l) + O₂(g) . Calculate $\Delta$ H_rxn° for this reaction from the enthalpies of the following reactions.
2 H₂(g) + O₂(g) $\rightarrow$ 2 H₂O(l)   $\Delta$ H_rxn° = -571.66 kJ/mol_rxn
H₂(g) + O₂(g) $\rightarrow$ H₂O₂(aq)   $\Delta$ H_rxn° = -187.8 kJ/mol_rxn

A) -759.5 kJ/mol_rxn
B) -383.9 kJ/mol_rxn
C) -196.0 kJ/mol_rxn
D) -98.0 kJ/mol_rxn
E) 196.0 kJ/mol_rxn
