Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2011 Problem Set No. 7 Due: Wednesday, February 23, 2011 Objective : To understand and perform calculations involving the entropy and the second law of thermodynamics for closed, open, and cyclical processes. Note: Numerical values for some problems have been changed from those in the book. Problem 32 ( thought problem) A well-insulated container consists of two halves of equal volumes separated by a partition. On one half there an ideal gas. On the other, there is a vacuum. The partition is suddenly removed, and the gas expands. Your friend suggests that the entropy change is zero since this is an adiabatic process for which gG 0 . What is wrong with his assessment? What is the actual entropy change per mol? Problem 33 ( Smith, van Ness, Abbott, 5.2, page 190) A Carnot engine receives 250 / of heat from a heat-source reservoir at 525 and rejects heat to a heat sink reservoir at 50...
