LOL!  Does the entropy not increase with time?

Reference:

1.)  Negative Absolute Temperature - Negative absolute temperatures (or negative Kelvin temperatures) are hotter than all positive temperatures, even hotter than infinite temperature.  Please note, they are using the text book definition of temperature (First snapshot below).

2.)  Negative Absolute Temperature for Motional Degrees of Freedom - An ensemble at positive temperature is described by an occupation distribution that decreases exponentially with energy.  If we were to extend this formula to negative absolute temperatures, exponentially increasing distributions would result.  However, the energy can be increased even further if high energy states are more populated than low-energy ones. In this regime, the entropy decreases with energy, which, according to the thermodynamic definition of temperature results in negative temperatures. The temperature is discontinuous at maximum entropy, jumping from positive to negative infinity. This is a consequence of the historic definition of temperature (Second & Third snapshot below).

Entropy is the Ultimate Order!

You are completely out of context.

Temperature is defined via entropy, so there's nothing to be taken out of context as you wrongly asserted with no explanation by you whatsoever.  Entropy is a measure of disorder in the system.  It is related to the number of energy states that are occupied by the particles: If only one energy state is occupied, as for example the lowest energy state in the case of a temperature of zero Kelvin, the system is very ordered and the entropy is zero. If the particles are however distributed over many energy states, low energy and high energy, the system is very disordered and the entropy is large.  Snapshot below showing how entropy defines temperature.

LOL, you commit the converse fallacy:  A is a member of B, therefore anything that is a member of B is therefore A.  Do whatever you can to put negative temperatures in the context of Profitis' electrochemical process.

It is you who is committing the converse fallacy, and not me!  This is another psychological projection of yourself, which we are so familiar with.  My reply was in response to your question of "Does the entropy not increase with time?"  I even quoted your question in my reply, so this is another intentional misdirection by you.  Your question had nothing to do with Profitis' electrochemical process itself, but had everything to do with entropy in general.  Now, you're trying to put a totally different context and meaning to my posts by mixing negative temperatures (temperature entropy) to Profitis' electrochemical process (electrochemical entropy).  My reply was to show how entropy is the 'ultimate order'!  Since entropy is the ultimate order, and electrochemical entropy has precedence over temperature entropy, then Profitis's electrochemical process should stand on it's own under the right conditions.
