Problem Set 4: Due by Mar. 29 in class Problem 1. One mole of ideal gas is compressed isothermally from 1 to 5 bar at 100 C. (a) What is the Gibbs energy change, G ? (b) What would have been the Gibbs energy change if the compression had been carried out at 0 C? Problem 2. In class, we derive one of the Maxwell relations. Derive all the four Maxwell relations. (a) P T T V P S (b) V S S P V T (c) P S S V P T (d) V T T P V S Problem 3. The Gibbs energy of a material is given by P b aT G ) ( where a , b and c are constants. Derive expressions for U , H and S of this material. Problem 4. Derive an expression for the entropy change ( S ) of isothermal expansion of 1 mole of van der Waals gas. The volume of this gas changes from V
