###### Problem Details

Consider the following reaction at constant P. Use the information here to determine the value of ΔSsurr at 398 K. Predice whether or not this reaction will be spontaneous at this temperature.

2 N2(g) + O2(g) → 2 NO2(g)                   ΔH = +163.2 kJ

A) ΔSsurr = -548 J/K, reaction is spontaneous

B) ΔSsurr = -548 J/K, reaction is not spontaneous

C) ΔSsurr = -410 J/K, reaction is not spontaneous

D) ΔSsurr = -410 J/K, reaction is spontaneous

E) ΔSsurr = -410 J/K, it is not possible to predict the spontaneity of this reaction without more information.
