Chemistry 4511 Problem Set 2 1. For the reaction 2CO 2 Æ 2CO + O 2 a. If there are initially 0.534 moles of CO 2 and 0.42 moles of CO are generated at some time, demonstrate that ξ is the same with respect to each component. b. Once the reaction goes to completion, there is a H value measured at T = 1000 K. Calculate the expected value for H two ways and compare the values (use heats of formation and bond enthalpies and adjust the H value away from standard T using C P ,m(T)) 2. An expandable vessel is filled with 1 mol of an ideal gas… a. The gas is compressed reversibly from 2L to 1L at a constant pressure and the temperature changes from 300K to 150K. What is the work done on the system? If U = -19 kJ/mol, then what is C p,m for the gas? b. The vessel is then made rigid and the temperature is dropped to 100K. What is U for this process? c. From here, T is held constant and the pressure is reversibly changed by +1.4 x 10 4 Pa. What is the work and heat derived from this process?
