Question: Silver carbonate, Ag2CO3, is a light yellow compound that decomposes when heated to give silver oxide and carbon dioxide: A researcher measured the partial pressure

Silver carbonate, Ag2CO3, is a light yellow compound that decomposes when heated to give silver oxide and carbon dioxide:

A researcher measured the partial pressure of carbon dioxide over a sample of silver carbonate at 220oC and found that it was 1.37 atm. Calculate the partial pressure of carbondioxide at 25oC. The standard enthalpies of formation of silver carbonate and silver oxide at 25oC are 505.9kJ/mol and 31.05 kJ/mol, respectively. Make any reasonable assumptions in your calculations. State the assumptions that you make, and note why you think they are reasonable.
