One mole of a monatomic perfect gas, initially at 298 K and 1 atm, expands irreversibly and isothermally against 0.5 atm, doing 400 J of work in the process. Calculate or explain the values of DU, DH, DG, q, DSsys, DSsurr and DStot. Also, calculate the reversible work for this isothermal change of state.
