Question: One mole of an ideal gas undergoes an isothermal reversible

One mole of an ideal gas undergoes an isothermal reversible expansion at 25oC. During this process, the system absorbs 855 J of heat from the surroundings. When this gas is compressed to the original state in one step (isothermally), twice as much work is done on the system as was performed on the surroundings in the expansion.
a. What is ΔS for the one-step isothermal compression?
b. What is ΔSuniv for the overall process (expansion and compression)?
