Let me first ask you this, is this a reversible or in irreversible process?
If it's a reversible process then the equality holds, but if it's irreversible, which means it happens spontaneously, t then ds is greater than this.
So a reversible process leads to requiring certain quantities to be maximized.
So this irreversible process this Joule-Thomson process, is a constant enthalpy process.
The dissolution was confirmed to be a quasi-reversible process, which was controlled by solid-state diffusion and charge transfer.
So we have first, a reversible process.
How many people vote for that this is a reversible process?
