(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using the exact differential, state function characteristics of S prove that ΔS for step I is always > 0 for an ideal gas expanding adiabatically and irreversibly from point 1 at TA,PA to point 2 at TB,PB

can anyone help me with this one?

A key difference this one has over others is that temperature is varied and thus not a normal adiabatic process where it mirrors an isothermal one

2. Relevant equations

first law, second law, helmholtz and gibbs free energy equations? mayb

3. The attempt at a solution

I basically got the same outcome as a adiabatic irreversible expansion identical to a isothermal equation but have a feeling the assumptions leading up that are wrong
