Chapter 17, Problem 17.71QE

Predict the temperature at which the reaction in Exercise 17.67 comes to equilibrium. Consider the equation ΔG = ΔH − TΔS. At some value of T, ΔG equals zero and the reaction is at equilibrium. Set ΔG = 0, substitute for ΔH° and ΔS° (assuming that they do not vary much with temperature) and solve for T.
