If 200 Mol of an Ideal Gas at 300 K and and 3.00

Multiple Choice

If 2.00 mol of an ideal gas at 300 K and 3.00 atm expands from 6.00 L to 18.00 L and a final pressure of 1.20 atm in two steps: (1) the gas is cooled at constant volume until its pressure has fallen to 1.20 atm,And (2) It is heated and allowed to expand against a constant pressure of 1.20 atm until its volume reaches 18.00 L,Which of the following is correct?

A) w = 0 for step (1) and w =-1.46 kJ for step (2)
B) w = -4.57 kJ for the overall process
C) w = -6.03 kJ for the overall process
D) w = -4.57 kJ for step (1) and w = -1.46 kJ for step (2)
E) w = 0 for the overall process
