molecules are described as isoelectronic
if they have the same number of valence
electrons in similar orbitals, although they may differ in their
distribution of nuclear charges (e.g., H-C N and H-N+ C-. Kineticpertaining
to the rates of chemical reactions.
A fast reaction
is said to have fast kinetics; if the balance of products in a reaction
is controlled by reaction
rates rather than by thermodynamic equilibria, the reaction
is said to be kinetically controlled.
