This isn't easy to answer without knowing (1) your background and (2) if this is a lab or industrial process, (3) the details of the reaction. So I'm going to refer you to the typical textbook we chemical engineers use for our Jr/Sr level undergrad reactor design course, "Elements of Chemical Reaction Engineering" by Scott Folger. RTD's of PFR's and CSTR's for various types of reactions and temperature dependence of are covered in that text/course.
If you need a copy, I'm sure you can find one on the internet. If you're not a chemical engineer / chemical engineering student, this might be outside your area of expertise.
