Consider the Following Reaction at Constant P

question 17

Multiple Choice

Consider the following reaction at constant P.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.
4 NH₃(g) + 3 O₂(g) → 2 N₂(g) + 6 H₂O(g) ΔH = -1267 kJ

• A)ΔS_surr = +12.67 kJ/K,reaction is not spontaneous
• B)ΔS_surr = -12.67 kJ/K,reaction is spontaneous
• C)ΔS_surr = +50.4 kJ/K,reaction is not spontaneous
• D)ΔS_surr = +3.18 kJ/K,reaction is spontaneous
• E)ΔS_surr = -3.18 kJ/K,it is not possible to predict the spontaneity of this reaction without more information.
