Gce Model Questions Vol1 2022 Chemistry Question 17
Practice objective / multiple choice question 17 from the 2022 Gce Model Questions Vol1 Chemistry examination.
The standard enthalpies of formation (Δ_fH°) of three binary oxides are: N₂O₅ : -11.3 kJ mol\(^{-1}\); P₄O₁₀ : -2984 kJ mol\(^{-1}\); SO₃ : -395.7 kJ mol\(^{-1}\). For each oxide (i) write the balanced reduction reaction to the element and O₂(g), (ii) calculate the enthalpy change per mole of O₂ released, and (iii) state which oxide is the strongest oxidising agent on a per‑O₂ basis.
