SUBROUTINE CKCVBL (T, X, ICKWRK, RCKWRK, CVBML)
Returns the mean specific heat at constant volume in molar units.

INPUT
T(*)      - Real array, temperature(s); dimension is determined by
            the application program to be the total number of
            species temperatures, nominally 1.
               cgs units, K
X(*)      - Real array, mole fractions of the mixture;
            dimension at least KK, the total species count.
ICKWRK(*) - Integer workspace array; dimension at least LENICK.
RCKWRK(*) - Real    workspace array; dimension at least LENRCK.

OUTPUT
CVBML     - Real scalar, mean specific heat at constant volume.
               cgs units, ergs/(mole*K)
