112.9 J/(K · mol) and AHfap = 38.0 kJ/mol is being A particular solvent with ASap = considered for an experiment. In the experiment, which is to be run at 75 °C, the solvent must not boil. Based on the overall entropy change associated with the vaporization reaction, would this solvent be suitable and why or why not? • View Available Hint(s) be suitable because ASuniv > 0. not be suitable because ASuniv > 0. The solvent would be suitable because ASuniy < 0. not be suitable because ASuniv < 0.

Consider the reaction - 4NO28) + 02(g) 2N205(g) at 25°C for which the following data are relevant: AHf S° N205 13.30 kJ/mol 355.7 J/K.mol NO2 33.15 kJ/mol 239.9 J/K.mol 02 O k/mol 204.8 J/K-mol Calculate AG° for the reaction at 25°C. 1.35 x 105 k 94.7 k 29.0 kj 135 k

Given Consider the Kp of the reaction C(s)  + CO2(g) <=> 2CO(g), with ∆H° of the reaction is -426 kJ. What is the effect of decreasing the reaction temperature to 298 K on the amount of CO gas produced?

One dissolves 15.00 grams CaCl2 in 100.0 grams of water. The final volume is 108.0 mL. The temperature is 298K. Calcium chloride is an ionic compound which dissociates in the following manner: CaCl2 (s) = Ca+2 + 2Cl-. The vapor pressure of water is 23.8 mm Hg at 298 K. From these data, calculate the following: Please show all work The % by mass of CaCl2 in this solution The molarity of this solution The molality of this solution The mole fraction of CaCl2 in this solution The vapor pressure of this solution The freezing point of this solution. Assume water freezes at 0o The boiling point of this solution. Assume water boils at 100oC The osmotic pressure of this solution. R = 0.08205 Liter-atm/mol K
