A turns into B, with rate constant k_{1}, which
turns into C, with rate constant k_{2}.

If k_{1} is slow and k_{2} is fast, then the
concentration of B is always low, as is illustrated in this
figure.

Alternatively, if k_{1} is fast and k_{2} is slow,
then the concentration of B will build up, then fall away:

To experiment with different values of k_{1} and k_{2},
type:

`demo1 k_{1} k_{2}`

An animation of the effect of changing the values of k

`demo2`

The demo version is rather smoother than this image:

It is also possible to display the effect of changing the ratio of k

`demo3d`
