Classical Kinetics

These web-apps allow you to set initial conditions and rate constants of reactions and view how the concentrations and rate change over time. The full derivation of formulae is provided.

A → B
A → 2B
2A → B
A + B → C
A → B | autocatalysis
A → B | zero order
A ⇌ B


Atomic Spectroscopy

Practice Term Symbols, draw vectors representing allowed electronic transitions on Grotrian diagrams and place the corresponding spectral lines where they are expected to be observed experimentally.

Electr. spectra: H, He+
Electr. spectra: Alkali


Separation Methods

This interactive suite of web-apps allows you to learn how to construct ternary diagrams and to design single and multi-step liquid–liquid extraction systems.
