Chapter 10, Problem 141CP

If wet silver carbonate is dried in a stream of hot air, theair must have a certain concentration level of carbondioxide to prevent silver carbonate from decomposingby the reaction
${\text{Ag}}_{\text{2}}{\text{CO}}_{\text{3}}\text{(}s\text{)}\rightleftharpoons {\text{Ag}}_{\text{2}}\text{O(}s{\text{)+CO}}_{\text{2}}\text{(}g\text{)}$
$\Delta H°$ for this reaction is 79.14 kJ/mol in the temperaturerange of 25°C−125°C. Given that the partial pressure ofcarbon dioxide in equilibrium with pure solid silver carbonateis $6.23\times {10}^{-3}$ torr at 25°C, calculate the partialpressure of ${\text{CO}}_{\text{2}}$ necessary to prevent decomposition of ${\text{Ag}}_{\text{2}}{\text{CO}}_{\text{3}}$ at 110.°C.
