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) ΔHo for this reaction is 79.14 kJ/ mol in the temperature range of 25oC–125oC. Given that the partial pressure of carbon dioxide in equilibrium with pure solid silver carbonate is 6.23 × 1023 torr at 25oC, calculate the partial pressure of CO2 necessary to prevent decomposition of Ag2CO3 at 110oC.
