Unformatted text preview: Given that = {(2a/RT)b}/C p,m with C p,m = 38.4 J K1 mol1 , a = 3.60 L 2 atm mol2 , and b = 0.44 L mol1 , calculate H for the process. 4. Derive the relation ( 29 ( 29 U T V T V V U C = from the expression for the total differential of U(T,V). 5. Starting from the expression ( 29 ( 29 P V v p T V T P T C C =, use the appropriate relations between partial derivatives to show that ( 29 ( 29 T P v p P V T V T C C =2 Evaluate C pC v for a perfect gas. 6. Derive an expression for the internal pressure of a van der Waals gas (see eqn 7.1) in terms of a, b, and V m . Use the expression to show that = {(2a/RT)b}/C p,m by using the definition of and appropriate relations between partial derivatives. (Hint: Use the approximation pV m RT when it is justifiable to do so.)...
