Given the following equation, N₂O(g) + NO₂(g) → 3 NO(g) Δ_rG° = -23.0 kJ mol^-1
Calculate Δ_rG° for the following reaction:
9NO(g) → 3N₂O(g) + 3NO₂(g)

Question

Given the following equation, N₂O(g) + NO₂(g) → 3 NO(g) Δ_rG° = -23.0 kJ mol^-1 Calculate Δ_rG° for the following reaction: 9NO(g) → 3N₂O(g) + 3NO₂(g)

Quizplus · Accepted Answer

The given reaction is the reverse of the original reaction multiplied by 3. Reversing the reaction changes the sign of ΔrG°, and multiplying by 3 scales it by 3. Thus, ΔrG° = 3 * 23.0 kJ mol⁻¹ = 69.0 kJ mol⁻¹.

Given the Following Equation, N2O(g) + NO2(g) → 3 NO(g)

Given the Following Equation, N₂O(g) + NO₂(g) → 3 NO(g)
