1. One mole of an ideal gas undergoes an isothermal reversible expansion at 300 K. During this process, the system absorbs 450 J of heat from the surroundings. When this gas is compressed to the initial state in one step isothermally, twice as much work is done on the system as was performed on the surroundings during the expansion. Which of the following statements about these processes are correct?
I. for the one-step isothermal compression is 1.5 J/K.
II. for the one-step isothermal compression is 3.0 J/K. 
III. for the reversible isothermal expansion is zero.
IV. for the overall process (expansion and compression) is zero.
V. for the overall process (expansion and compression) is -1.5 J/K.
(A)I,II
(B)Ⅱ,Ⅲ
(C)Ⅱ,Ⅲ,IV
(D)Ⅱ，Ⅲ，V
(E)I,IV,V
