CHEM 342 Physical Chemistry I, (Fall 2010) Problem set 4 Due 10/26/2010 (Monday) 1. Textbook 4.4 or 4.6. 2. Textbook 4.24 3. Textbook 4.30 or 4.32. 4. Textbook 4.38. 6. Derive the relationship between T and V for an ideal gas in an adiabatic reversible process. Instead of starting from the exact differential for dU, start from the dH differential. Do you get the same results in both cases? 7. Study the following heat engine with 3 moles of ideal gas and the four-stroke closed circle (C v m =2.5R, P 1 = 3 atm, T 1 =300K): Step 1: reversible adiabatic expansion to P 2 = 2 atm Step 2: isothermal compression against constant external pressure P ex until V 3 Step 3: reversible expansion following the path with a constant slope dP/dV=1 atm/L until the final pressure of P 4 = 3 atm (initial pressure) Step 4: constant-pressure reversible compression going back to the starting point (1) Calculate w, q, U, H , S in each steps an their total value. What is the (exact/approximate) change of entropy for the
