Evaporatio with chemical reaction

Hi, I've got this problem: I have a droplet composed of water and urea that evaporate in a hot gas flow. First evaporate all the water than solid urea thermolize ... co(nh2)2 <s>---> nh3<g>+conh<g> (endotermic). I've try to use a non pre mixed model of combustion but default ask me a gas fase oxidase species. I've have to use surface chemical reaction model? But how can I say to the program that the reaction begins when the water is completly evaporate from the drop?
