BMB428 Dr. Song Tan Physical Chemistry with Biological Applications Fall 2007 1 1. Problem 5.10 (p. 187): Calculate the changes in entropy for the following processes: (a) mixing of 1 mole of nitrogen and 1 mole of oxygen, (b) mixing of 2 moles of argon, 1 mole of helium, and 3 moles of hydrogen. Both (a) and (b) are carried out under conditions of constant temperature (298 K) and constant pressure. Assume ideal behavior. 2. Problem 5.16 (p. 187): A miner working 900 ft below the surface had a soft drink beverage during the lunch break. To his surprise, the drink seemed very flat (that is, not much effervescence was observed upon removing the cap). Shortly after lunch, he took the elevator up to the surface.
