Determine Δ_rG° at 298 K using the following information: H₂(g) + CO(g) → CH₂O(g) Δ_rH°= +1.9 kJ mol^-1; Δ_rS°= -109.6 J K^-1mol^-1

Question

Quizplus · Accepted Answer

Δ_rG° can be calculated using the formula Δ_rG° = Δ_rH° - TΔ_rS°. Substituting the given values: Δ_rG° = 1.9 kJ/mol - (298 K)(-109.6 J/K/mol)(1 kJ/1000 J) = 1.9 kJ/mol + 32.672 kJ/mol = 34.572 kJ/mol, which rounds to +34.6 kJ/mol.
