1. (Use picture for this question) What is the solubility ofcarbon monoxide gas (in mg/100 g of water) at 0, 20, and 40 degreesCelcius?
2. A solution is made by mixing 112. g of chloroform (CHCl3) and54. g of acetyl bromide (CH3COBr). What is the mole fraction ofacetyl bromine?
3. What would you expect the Van't Hoff factor for Fe2(SO4)3 tobe?
Effect of Temperature on the Solubility of Gases The solubility of gases in liquids decreases with increasing temperature. •As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases. Solubility (mg/100 g H₂O) 10 ! 2 0 10 20 Temperature (°C) 30 26852 NO CO CH4 N₂ 40
