Question 11

Multiple Choice

Determine △H° for the decomposition of hydrogen peroxide. H2O2(l) → Determine △H° for the decomposition of hydrogen peroxide. H<sub>2</sub>O<sub>2</sub>(l) → O<sub>2</sub>(g) + H<sub>2</sub>O(l) Given: H<sub>2</sub>(g) + O<sub>2</sub>(g) → H<sub>2</sub>O<sub>2</sub>(l) △H° = -187.78 kJ H<sub>2</sub>(g) + O<sub>2</sub>(g) → H<sub>2</sub>O(l) △H° = -285.83 kJ A) -98.05 kJ B) +93.89 kJ C) -191.94 kJ D) -93.89 kJ O2(g) + H2O(l)
Given: H2(g) + O2(g) → H2O2(l) △H° = -187.78 kJ
H2(g) + Determine △H° for the decomposition of hydrogen peroxide. H<sub>2</sub>O<sub>2</sub>(l) → O<sub>2</sub>(g) + H<sub>2</sub>O(l) Given: H<sub>2</sub>(g) + O<sub>2</sub>(g) → H<sub>2</sub>O<sub>2</sub>(l) △H° = -187.78 kJ H<sub>2</sub>(g) + O<sub>2</sub>(g) → H<sub>2</sub>O(l) △H° = -285.83 kJ A) -98.05 kJ B) +93.89 kJ C) -191.94 kJ D) -93.89 kJ O2(g) → H2O(l) △H° = -285.83 kJ
