a) Calculate the work in J obtained from the reversible expansion of 0.2 mol of krypton from 4.25 L to 6.50 L at 298 K. b) Would the work obtained when expanding krypton from the same initial to final state as above but with a constant external pressure of 0.5 atm be larger or smaller than the reversible work computed in part a? Calculate the value or provide a conceptual explanation for your choice.
