1、So we have first, a reversible process.

2、How many people vote for that this is a reversible process?

3、They created a similar but reversible process that can either consume or release energy.

4、So a reversible process leads to requiring certain quantities to be maximized.

5、The dissolution was confirmed to be a quasi-reversible process, which was controlled by solid-state diffusion and charge transfer.

6、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.
