In a Certain Reversible Expansion, a System at 300

Multiple Choice

In a certain reversible expansion, a system at 300. K absorbs exactly 6.00 × 10² J of heat. In the irreversible recompression to the original state of the system, twice as much work is done on the system as is performed on the surroundings in the expansion. What is the entropy change of the system in the recompression step?

A) 0.00 J/K
B) 2.00 J/K
C) -4.00 J/K
D) -2.00 J/K
E) 4.00 J/K
