The standard molar entropy value of N2 (g) is 191.5 J/K-mol,

of O2 (g) is 205.0 J/K-mol and of NO2 (g) is 240.0 J/K-mol. From these values

we can calculate the Delta S for the reaction N2 (g) + 2 O2 (g) produces 2 NO2 (g) to be

a. – 156.5 J/K

b. 636.5 J/K

c. 15.5 J/K

d. – 121.5 J/K

e. – 83.5 J/K
