2.
A system consists of 1 mole of ideal gas is taken through the cycle shown below
from (1→2 →3). For this ideal gas, Cp = 5R/2 and C+ = 3R/2
(a) Determine the temperature (in units of K to 4 sig. figs) at the points, 1, 2, and 3
For (b), (c), and (d) please report q, w, AU, and AH in units of kJ to 3 sig. figs. If an answer is 0, then
just put 0 for the answer.
(b) Calculate q, w, AU, and AH for step 1-2 (in other words as the system is taken from an initial
state at point 1 to a final state at point 2)
(c) Calculate q, w, AU, and AH for step 2→3
(d) Calculate q, w, AU, and AH for step 3→1
