jaydeeSo I got started on the second draft of my Physical Chemistry assignment today. 700 words written out of 3000. Three thousand words for an assessment item worth 6% of the final mark. Ugh. But I'm having fun with it - my current first line is "It was a dark and stormy night", and my first draft looked like this:
To understand electrochemistry
behaviour of solutions must be known,
not concentration, but activity
is used, because ions are not alone.
A way to model this has been proposed
by Debye and Hückel, who wrote a law
to find activity, where they supposed
it was Coulumbic forces, with a more
appropriate value for epsilon:
the permittivity of the solvent.
First they considered with no forces on
the ions, then with charges on, which meant
the chemical potential changes could
reveal the co-efficient. Which is good.
