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)
∆h° is 79.14 kj/rxn for this reaction in the temperature range 25 to 125°c. given that the partial pressure of carbon dioxide in equilibrium with pure solid silver carbonate is 6.23 x 10-3 torr at 25°c, calculate the partial pressure in torr of co₂ necessary to prevent decomposition of ag₂co₃ at 99°c.
