Dear Dr. Li,
Thank you for your submission to ACPD and for providing your comments/response to the reviewers. I have reviewed your response and believe you have adequately addressed the issues raised by the reviewers.

I have a few additional questions that I’d like your response on before making a decision:
1. Wall-loss correction: Particle wall loss is size dependent; however, here the correction is based on integrated mass. If you apply size dependent particle loss correction, how different would the results be?
2. What is the estimated OH in the pure and mixture experiments? How similar is the reactivity with respect to OH during pure and mixture experiments? How does this reactivity compare to that of NO2? Why was so much hither initial conc. of 1,3,5- TMB used compared to dodecane?
3. Since the experiments were carried out under high NOx, it’s likely that some nitric acid also partitioned in the aerosols. It seems the total volume increase is assigned to be due to SOA formation. What is the magnitude of the error associated with this assumption?

Editorial corrections:
1. L170: sentence after “however” needs to be rephrased.
2. L184: change “likely not this case here” to “likely not the case here”
3. L194: products “have”
4. L195: coagulate is not the right phrase here; consider “condense” instead
5. L198: consider changing to “different injection experiments….”
6. L236: change has to have
7. L247: change “are existed” to “exist”
8. L248: what do you mean by “and the relative strength is mixed”? Please clarify
9. L253-254: consider deleting “In this work” and “mainly”
10. L268: the lines before discuss ozone formation; however the sentence starting with “In conclusion”, discusses results related to particle formation. This logic doesn’t make sense. Please make sure the sentences are not misplaced with that of the next section, i.e., L280-282 that discuss ozone formation.
11. L276, change 1.3.5 to 1,3,5-
12. L594- description for © needs to be rephrased.
13. Figure 3 caption: “changement” is not correct. Please use a different word.

Looking forward to receiving your response.
