If wet silver carbonate is dried in a stream of hot air, the air must have a certain concentration level of
carbon dioxide to prevent silver carbonate from decomposing by the reaction
Ag2CO3 (s) Ag2O(s) + CO2(g)
∆ for this reaction is 79.14 kJ/mol in the temperature range of 25C to 125C. Given that the partial
pressure of CO2 in equilibrium with pure solid silver carbonate is 6.23 x 10-3 mm Hg at 25C, what is the
partial pressure of CO2 necessary to prevent the decomposition of Ag2CO3 at 110C?
I realize that delta X isn't labeled in the question. I'm not sure if it's supposed to be G, S, or H, but I'm sure if you can figure this question out, you'll know what it should be. the answer is 7.49mmHg. how do I get there? thanks
