Question 1

Find ΔH°rxn for the reaction
         CH4(g) + 2O2(g) → CO2(g) +  2H2O(l).
         [ΔH°f (CH4(g)) = –74.8 kJ/mol; ΔH°f (CO2(g)) = –393.5 kJ/mol; ΔH°f (H2O(l)) = –285.5 kJ/mol]


Question 2

Given the following ΔH° values,
         H2(g) + O2(g) → H2O(l)   ΔH°f = –285.8 kJ/mol
         H2O2(l) → H2(g) + O2(g)     ΔH°rxn = 187.6 kJ/mol
calculate ΔH°rxn for the reaction H2O2(l) → H2O(l) + O2(g),
