Consider the Following Reaction at Constant Pressure

question 10

Multiple Choice

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

• A) ?S surr = +114 kJ K -1 mol -1 , reaction is spontaneous
• B) ?S surr = +114 kJ K -1 mol -1 , reaction is not spontaneous
• C) ?S surr = +321 J K -1 mol -1 , reaction is spontaneous
• D) ?S surr = -321 J K -1 mol -1 , reaction is not spontaneous
• E) ?S surr = +321 J K -1 mol -1 , reaction is not spontaneous
