You will probably have to adjust your 4-step model so that STAR-CD can handle it - see their requirements for entering reactions under Local Source Reaction Schemes in chapter 12 in the User Guide. Note that this is not always possible. As to the rate constants - reduced models usually do NOT follow simple Arrhenius expressions as you require, and you will probably have to write your own reaction routine (reacfn.f).
