Consider the Following Reaction at Constant P

question 99

Multiple Choice

Consider the following reaction at constant P.Use the information here to determine the value of ΔS_surr at 355 K.Predict whether or not this reaction will be spontaneous at this temperature. 2 NO(g) + O₂(g) → 2 NO₂(g) ΔH = -114 kJ

• A) ΔS_surr = -114 kJ/K, reaction is spontaneous
• B) ΔS_surr = +114 kJ/K, reaction is spontaneous
• C) ΔS_surr = +321 J/K, reaction is spontaneous
• D) ΔS_surr = -321 J/K, reaction is not spontaneous
• E) ΔS_surr = +114 J/K, it is not possible to predict the spontaneity of this reaction without more information.
