determine the
H for the following equation.

2H2O2(l) → 2H2O(l) + O2(g)

Use the following known enthalpies of formation:

ΔH∘f(H2O2) = −188 kJ/mol
ΔH∘f(H2O) = −286 kJ/mol
ΔH∘f(O2) = 0 kJ/mol

and

∆H0 = sum of [(∆Hf0 of products) × (mol of products)]– sum of [(∆Hf0of reactants) × (mol of reactants)]

Group of answer choices

+ 98 kJ/mol

- 196 kJ/mol

- 98 kJ/mol

+ 196 kJ/mol
