Oxygen    gas initially    at    355 K    and    1.50 bar    undergoes the    following    cyclic    processes    in    a    closed    system:
Step    1:    Adiabatic    compression    to    7.50 bar
Step    2:    Addition    of    13    240.0 J/mol    of    heat    to    raise    the    temperature    at    constant    pressure
Step    3:    Adiabatic    expansion    to    1.50 bar
Step    4:    Isobaric    cooling    back    to    original    state.
Determine    ΔU,    ΔH,    Q    and    W    for    each    step,    and    for    the    overall    reversible    process.    Express    all answers    in    kJ/mol
and    up to    decimal places
