What are my chances at the top 10-30ish programs in Chemistry?

I am a female international student, got my BS in the US. I'm finishing my application but I think I'm not applying to enough schools. 

Undergrad School: A small, non-research, liberal art women's college in the US

Undergrad Major: Chemistry                                      Undergrad GPA: 3.95 out of 4.0

GRE: Q = 170 , V = 157 , AW = 5.0                 TOEFL iBT:  114 (S = 25)                                    Chemistry Subject GRE:  I bombed it, so I won't send it in unless it says "highly recommended"

Courses: I had all the basic required Chemistry classes except Inorganic Chemistry

                Took the only advanced Chem class available (Advanced Organic Spectroscopy)

Research Experience: _1.5 years working at an oceanography lab on 2 projects

                                       _ 2 independent projects on trivial stuff (method developments)

                                       _ 2 internships at the state's toxicology lab (building reference library) and an industrial R&D lab (work on a method development projects)

                                       _ A bunch of independent mini-research projects for classes.

                                      _ All of my research projects (big or small, academic or industrial) are presented at either school/Southern regional seminars and conferences. No publication

Other relevant info:   _ Award for outstanding chemistry senior, award for academic achievement, members of honor societies

                                      _ 3 years working as a tutor for Sciences classes

LORs: _One solid letter from my professor (taught me 5 classes and oversaw my projects)

            _One okay-good one from my lab's PI (pretty famous in her field, but I'm not applying to her field unfortunately lol)

            _One good one from my academic advisor

SOPs: I'm tailoring my SOP to each program I'm applying to make sure my interest and experience are relevant to the said program. 

Applying: Duke, Purdue, Northwestern, Carnegie Mellon, GaTech, Emory

Am I aiming too high for schools in the 30s rank? I try to apply to private institutions tho. What are other programs should I try that would be more in my range? Also, is it too late now to contact professors?

Thank you for your input!

Might be too late for this but I'm aapplying to physical chem PhD this cycle and I think you might have aimed too low for 30ish. My GPA is 3.6, verbal GRE is 163. Did 1.5 years research in organic chemistry and 0.5 year in computational physics. Just got into UT Austin and Carnegie Mellon. UT Austin is ~15 for physical chemistry and ~15 overall in chem. Carnegie Mellon is ~40 overall in chem. Your stats look better than mine, so yeah, I have a feeling you aimed too low.
