Solution: From the following information, determine ΔS°298 for the following:N(g) + O(g)⟶NO(g)                ΔS° 298 = ?N2(g) + O2(g)⟶2NO(g)          ΔS° 298 = 24.8 J/KN2(g)⟶2N(g)                           ΔS°  298 = 115.0 J/KO2(g)⟶2O(g)                          ΔS°  298 = 117.0 J/K

Problem

From the following information, determine ΔS°298 for the following:

N(g) + O(g)⟶NO(g)                ΔS° 298 = ?

N2(g) + O2(g)⟶2NO(g)          ΔS° 298 = 24.8 J/K

N2(g)⟶2N(g)                           ΔS°  298 = 115.0 J/K

O2(g)⟶2O(g)                          ΔS°  298 = 117.0 J/K
