A sample of 0.50 moles of O2 gas initially at 250K and a pressure of 1.0 atm is compressed to final pressure of 12 atm. The compression can occur via two different paths: 1) adiabatic and reversible 2) adiabatic and irreversible in external pressure of 15 atm. For each case, calculate the values of q, w, delta U, delta H in unit of J
