  The partition of decay energy between the kinetic energy of reaction products
and their Q-value of formation is obtained in a statistical derivation
appropriate to highly excited nuclei, and is shown to be in a constant ratio.
We measure the kinetic energy fraction, $R = \Sigma E_{kin}/(\Sigma E_{kin} +
\Sigma Q_0)$, over a wide range of excitation energy for well-defined systems
formed in the Cl + C reaction at 35A MeV. Relationships between excitation
energy, charged-particle multiplicity, and intermediate-mass-fragment
multiplicity, observed in this work and in recent experiments by a number of
other groups, follow from the derivation of the average kinetic energies and
Q-values.
