A sample of 35 millimole of Krypton gas expands reversibly and isothermally at 373K from 5.25 cubic centimeters to 6.29 cubic centimeters. The internal energy, U, increases by 41.75 J. Use the Virial equation of state with B=(-28.7)(cubic centimeters)/(mole) to calculate work, q, and delta H for this change.
