Table 5.10: Chemical Production Rates Subroutines

Subroutine	Description
`SUBROUTINE SKCONT (KSPEC, ROP, ISKWRK, RSKWRK, CIK)`	Returns the contributions of the surface reactions to the molar production rate of species KSPEC.
`SUBROUTINE SKDRDA (IR, P, T, ACT, SDEN, ISKWRK, RSKWRK, DKDAI)`	Returns the partial of the rates of production of the species with respect to the pre-exponential constant of surface reaction IR.
`SUBROUTINE SKDRDC (KSPEC, P, T, ACT, SDEN, ISKWRK, RSKWRK, DKDC)`	Returns the partial derivative of the production rates of the species with respect to the concentration of species KSPEC.
`SUBROUTINE SKDSDC (P, T, X, ACT, SDEN, ISKWRK, RSKWRK, DSDC, KKTOT, SDOT, SITDOT)`	Returns the partial derivative of the production rates of the species with respect to the concentration of each species. It also returns the matching production rates.
`SUBROUTINE SKDSDX (P, T, X, ACT, SDEN, ISKWRK, RSKWRK, DSDX, KKTOT, SDOT, SITDOT)`	Returns the partial derivative of the production rates of the species with respect to the activity for each species. It also returns the matching production rates.
`SUBROUTINE SKRAT (P, T, ACT, SDEN, ISKWRK, RSKWRK, SDOT, SITDOT)`	Returns production rates for the species and sites.
`SUBROUTINE SKRATI (IR, ROP, ISKWRK, RSKWRK, SDOTI, SITDTI)`	Returns rates of production of the species by surface reaction IR.
