ΔH°_f for CO(g) = -110.5 kJ/mol

Question

Using the information below, calculate ΔH°_f for PbO(s).PbO(s) + CO(g) → Pb(s) + CO₂(g), ΔH° = -131.4 kJ ΔH°_f for CO₂(g) = -393.5 kJ/mol ΔH°_f for CO(g) = -110.5 kJ/mol

Quizplus · Accepted Answer

To find ΔH°_f for PbO(s), use the equation: ΔH° = ΔH°_f(products) - ΔH°_f(reactants). Rearrange to find ΔH°_f(PbO): ΔH°_f(PbO) = ΔH°_f(CO₂) + ΔH°_f(Pb) - ΔH°_f(CO) - ΔH°. Substituting the values: ΔH°_f(PbO) = (-393.5) + 0 - (-110.5) - (-131.4) = -151.6 kJ/mol.
