For the reaction in Example 19.6, estimate the value of ΔG°_rxn at 125 °C. Is the reaction more or less spontaneous at this elevated temperature? That is, is the value of ΔG°_rxn more negative (more spontaneous) or more positive (less spontaneous)?

Example 19.6

One of the possible initial steps in the formation of acid rain is the oxidation of the pollutant SO₂ to SO₃ by the reaction:

Calculate ΔG°_rxn at 25 °C and determine whether the reaction is spontaneous.
