Measuring activities with a Knudsen cell

[lalbatros]

Hello

I would like to find some texts or web sites explaining how and why activities can be measured with a Knudsen cell. What is measured and how the Gibbs energy is deuced from the measurements.

I would also like to find out the range of application of this method, like for temperatures.

Thanks,

Michel

I've actually researched a bit on electric cells, perhaps you can find something here (try to browse under electrolysis etc)
