In regards of the following reaction at constant P. Utilize the information here to conclude the value of? Ssurr at 398 K. Calculate whether or not this reaction will be spontaneous at this temperature.
4 NH3(g) + 3 O2(g) ? 2 N2(g) + 6 H2O(g) ?H = -1267 kJ
A) Ssurr = +12.67 kJ/K reaction is not spontaneous
B) Ssurr = -12.67 kJ/K reaction is spontaneous
C) Ssurr = +50.4 kJ/K reaction is not spontaneous
D) Ssurr = +3.18 kJ/K reaction is spontaneous
E) Ssurr = -3.18 kJ/K it is not possible to predict the spontaneity of this reaction
