Consider the Following Reaction at Constant Pressure

question 62

Multiple Choice

Consider the following reaction at constant pressure. Use the information here to determine the value of ΔS_surr at 398 K. Predict whether or not this reaction will be spontaneous at this temperature. 4NH₃(g) + 3O₂(g) → 2N₂(g) + 6H₂O(g) Δ_rH = -1267 kJ

• A) ΔS_surr = +12.67 kJ K^-1 mol^-1, reaction is not spontaneous
• B) ΔS_surr = -12.67 kJ K^-1 mol^-1, reaction is spontaneous
• C) ΔS_surr = +50.4 kJ K^-1 mol^-1, reaction is not spontaneous
• D) ΔS_surr = +3.18 kJ K^-1 mol^-1, reaction is spontaneous
• E) ΔS_surr = -3.18 kJ K^-1 mol^-1, reaction is not spontaneous
