Snowflake network

Example 6.3 Rate equations for hypothetical "snowflake" network. For the eight-node, ten-ended, fully reversible, reduced "snowflake" network... 

In this fashion, network portions can be linked to one another and rate equations in terms of A coefficients be obtained by appropriate substitutions as in eqns 6.34 to 6.36 and 6.30. For example, in the snowflake network 6.21, two pairs of single-node portions 6.28 are linked at their respective common intermediate Xm and the two resulting larger portions are linked to a fifth single-node portion. This procedure eliminates all node intermediates and leads to the described Chem algorithm. 

If all possible hydrogen bonds form in a mole (Na molecules) of pure water, then every oxygen atom is surrounded by four H atoms in a tetrahedral arrangement its own two and two from neighboring molecules. This tetrahedral arrangement forms a three-dimensional network with a structure similar to that of diamond or SiOi. The result is an array of interlocking six-membered rings of water molecules (Fig. 10.14) that manifests itself macroscopically in the characteristic sixfold symmetry of snowflakes.
