Question

True or false, please explain why. If a sample of helium of mass 6.56g occupies 18.5 dm^3 at 305 K, the work done when the gas expands isothermally against a constant external pressure of 7.7 KPa until its volume has increased by 2.5 dm^3 is larger than the work that would be done if the same expansion occurred reversibly.
