Re: Reversible vs Irreversible
Generally the question will deliberately state whether a system is reversible or irreversible.
For reversible systems:
w= -nRTln(V2/V1)
ΔS= q(rev)/ T @ a constant temperature
ΔS (where T1 --> T2) = nCln(T2/T1)
For irreversible systems:
w=-PΔV
ΔS= nRln(V2/V1)
For reversible systems:
w= -nRTln(V2/V1)
ΔS= q(rev)/ T @ a constant temperature
ΔS (where T1 --> T2) = nCln(T2/T1)
For irreversible systems:
w=-PΔV
ΔS= nRln(V2/V1)

Re: Reversible vs Irreversible
^^ Adding onto Faith’s answer:
For reversible, the question will also state that system is isothermal.
Also, Ssys is the same for irreversible and reversible work.
The only difference is Ssurr.

Re: Reversible vs Irreversible
Also remember that irreversible processes have more entropy than reversible processes.
