SUBROUTINE CKCDC  (T, C, ICKWRK, RCKWRK, CDOT, DDOT)
Returns the molar creation and destruction rates of the species
given temperature(s) and molar concentrations.

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
C(*)      - Real array, concentrations of the species;
            dimension at least KK, the total species count.
               cgs units, mole/cm**3
ICKWRK(*) - Integer workspace array; dimension at least LENICK.
RCKWRK(*) - Real    workspace array; dimension at least LENRCK.

OUTPUT
CDOT(*)   - Real array, chemical creation rates of the species;
            dimension at least KK, the total species count.
               cgs units, mole/(cm**3*sec)
DDOT(*)   - Real array, chemical destruction rates of the species;
            dimension at least KK, the total species count.
               cgs units, moles/(cm**3*sec)
