A piston performs 450 L*atm of irreversible work on the surrounding, while the cylinder in which it is placed expands from 10. L to 25L. At the same time, 45 J of hear is transferred from the surroundings to the system. Against what pressure (in atm) was the piston working? Calculate the REVERSIBLE work if the piston is at 300.K and 2. moles of ideal gas are in the piston.
