Chapter 17, Problem 17.139(choose chapter or problem)
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 1s2mAg2O1s2 1 CO2 1g2 DH8 for this reaction is 79.14 kJ/mol in the temperature range of 25 to 1258C. Given that the partial pressure of carbon dioxide in equilibrium with pure solid silver carbonate is 6.23 3 1023 torr at 258C, calculate the partial pressure of CO2 necessary to prevent decomposition of Ag2CO3 at 110.8C. (Hint: Manipulate the equation in Exercise 79.)
