Units of entropy: what should they now be?
« on: 03/02/2020 11:18:04 »
I think the best units of entropy for thermochemical equations should now be:
KJ/Mol/second,  as the rate of a reaction is fundamental to entropy.  if a reaction reacts faster it would likely be more entropic.  similarly, this amount varies with temperature.  Usually, the higher the temperature,  the more entropy there would be, but not always.  so a chart for each thermochemical equation , one for enthalpy and one for entropy should both be made.   both with kJ/Mol/s vs. Kelvin.
This will need a complete rewrite for the thermochemistry section of the CRC handbook of physics and chemistry.
I have heard that the japanese have already got charts on this, but that might be  rumour.

also as an aside there are now two units known to science that 2+2=4 is not necessarily valid for,  and one is entropy and one is grandparents,  the second kind of being a joke, but really the same thing as the first actually.
-2+-2 might actually be -8 with negative entropy.
there are several equations that probably have negative entropy
like the polyester equation,   if you make polyester with it it costs energy and money but you can sell the product for more than the cost of the energy and money needed to make it, so that is negative entropic.   also if you burn the polyester you can get energy from it,  but that might be toxic and destructive , so that would be entropic.
Try to find equations that are negative entropic both ways.
I believe the syngas equations,  CO + H2+O2 <>CO2 + H2O  is probably negative entropic both ways and may save the earth from continually rising CO2 levels when formed in the reverse direction.

Those units are not the units of entropy which is J/T, so you are talking about something different than entropy. 

For entropy all that matters is the change in the energy over a change in temperature. 

Moles are not needed because that is already taken into account by the change in energy.  IOW the energy involved in 1 molecule is a lot lower than the energy in 6.02 x 10^23 molecules.  The time is also taken into account because the energy change will necessarily occur over some time frame.

As I have shown we will luckily not have to change all science books.  Uh, it was a rumour...

More good news we will not have to change the laws of addition, -2 + -2 does not equal 8.

Negative entropy?  I think you mean a decrease in entropy.
If you boil water you are increasing the entropy of the water molecules as they turn to steam.  When the steam condenses on a cold window pane the entropy of the water molecules decreases.  No big deal.
