A small solvent molecule has the following properties: molar heat capacity of the liquid at constant pressure
Question:
A small solvent molecule has the following properties: molar heat capacity of the liquid at constant pressure CP = 15.7 l/mole-K; Wolar heat capacity of the gas at constant pressure G = 5.12 J/mole-K, boiling point for the liquid at 1 atm pressure - 43.4°C; heat of vaporization of the liquid at 1 atm pressure and 43.4°C -4440 J/mole. 1.77 moles of the substance is converted from initial conditions of a liquid at P = 1.00 atm and T = 10.0°C to the final conditions of a gas at P= 2.00 atm and Tee 150."C. You may regard the solvent in the gas phase as an ideal gas. Calculate for the process: q, w, AH, AU. (Hint: Outline how you might take the system from the initial conditions to the final conditions changing only one parameter at a time, but be careful how you do it!). (g = 3.45, W=0, AU = 3.45 KJ, AH 9.68K)
