Standard Entropy Values - A through B
Standard entropy values indicate the absolute entropy (in \(\unit{\joule\per\mole\per\K}\)) of a variety of substances beginning with A through B at \(25\unit{\degreeCelsius}\). Learn more on our Tutorial page.
This sub section was created since the full list contained over 1000 elements which was too much for most devices to render. You can also get the full listing in PDF (not accessible) here: Download as PDF File. Below are the other formula breakdowns:
- Entropy Values with Formula A through B
- Entropy Values with Formula C
- Entropy Values with Formula D through K
- Entropy Values with Formula L through O
- Entropy Values with Formula P through Z
Visually impaired users can use their screen readers built in search to search for the substance (no spaces, subscript and superscripts just as normal inline letters) and quickly navigate to the row.
Substances and their entropy values (in joules per mole per kelvin) at 25 degrees Celsius. A searchable version of the substance chemical formula has been placed. You can use the browser built in search to search for the compound, typing everything in one line (all subscript and superscripts for this search are just normal numbers with no spaces between).
