Problem

A reaction that occur in the internal combustion engine is

N2(g) + O2(g) ⥫⥬ 2NO(g)

(a) Determine ΔH° and ΔS° for the reaction at 298 K.
(b) Assuming that these values are relatively independent of temperature, calculate ΔG° at 100.°C, 2560.°C, and 3540.°C.
(c) What is the significance of the different values of ΔG°?

(d) At what temperature (in K) does the reaction become spontaneous?
