Isothermal Expansion Work Calculation

Hard General Chemistry Thermodynamics And Thermochemistry

In the context of thermodynamics, consider a closed system containing one mole of an ideal gas undergoing an isothermal expansion from an initial volume of 10.0 L to a final volume of 20.0 L at a temperature of 300 K. Using the ideal gas law and the first law of thermodynamics, which of the following statements about the work done by the gas during this process is true?

The work done by the gas is equal to -RT ln(Vf/Vi).

The work done on the gas is positive and equal to RT ln(Vf/Vi).

The work done by the gas is positive and equal to RT ln(Vi/Vf).

The work done by the gas is zero since the temperature remains constant.
