      There is defect with Fluent surface reactions where the text widgets for the product concentration exponents are greyed out the first time the reaction panel is visited (or when a surface reaction is first created). Exiting the species model panel (accepting all changes) and then Editing the reactions again should allow you to specify the product Rate exponents. Note that if reverse reaction is selected, Rate Exponents will stay greyed out.
