Question 90

Short Answer

Given the following Δ\Delta H° values,
H2(g)+  Given the following  \Delta H° values, H<sub>2</sub>(g)+   O<sub>2</sub>(g) \rarr H<sub>2</sub>O(l), \Delta H°<sub>f</sub> = -285.8 kJ/mol H<sub>2</sub>O<sub>2</sub>(l), \Delta  H<sub>2</sub>(g)+ O<sub>2</sub>(g), \Delta H°<sub>rxn</sub> = 187.6 kJ/mol calculate  \Delta H°<sub>rxn</sub> for the reaction H<sub>2</sub>O<sub>2</sub>(l) \rarr  H<sub>2</sub>O(l)+   O<sub>2</sub>(g), O2(g) \rarr H2O(l), Δ\Deltaf = -285.8 kJ/mol
H2O2(l), Δ\Delta H2(g)+ O2(g), Δ\Deltarxn = 187.6 kJ/mol
calculate Δ\Deltarxn for the reaction H2O2(l) \rarr H2O(l)+  Given the following  \Delta H° values, H<sub>2</sub>(g)+   O<sub>2</sub>(g) \rarr H<sub>2</sub>O(l), \Delta H°<sub>f</sub> = -285.8 kJ/mol H<sub>2</sub>O<sub>2</sub>(l), \Delta  H<sub>2</sub>(g)+ O<sub>2</sub>(g), \Delta H°<sub>rxn</sub> = 187.6 kJ/mol calculate  \Delta H°<sub>rxn</sub> for the reaction H<sub>2</sub>O<sub>2</sub>(l) \rarr  H<sub>2</sub>O(l)+   O<sub>2</sub>(g), O2(g),
