Thank you for your kind recommendation.
Reviewer 2 Report (Previous Reviewer 1)
Dear Author(s);
Manuscript is well written and there is need of minor revision. Comments are attached;
1. Improve justification of this study in Line 89-92.
2. Re-write sentence in line 45-46.
3. Formatting issue (line 49).
4. From the table, it is seen that polarization resistance increased from 54.46 W cm2 in the uninhibited solution to 219.97 W cm2 on introduction of 0.1% composite to the corrosive medium corresponding to IE of 75.24%. (line 402-404). Give possible reason. Also add relevant citation.
5. Examination of the table shows that both Rct and Rp decline with rise in temperature. (line 563). Give possible reason. Also add relevant citation.
6. The values for inhibitory efficiency decline proportionally with temperature. (line 632). Give possible reason. Also add relevant citation.
7. Use good quality tables (a & b) in figure 13.

Reviewer 3 Report (Previous Reviewer 2)
The authors reviewed the manuscript and accepted all the reviewer's suggestions properly. Good work.
Author Response
We are grateful to the reviewer for the kind recommendation.
This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.
Round 1
Reviewer 1 Report
Dear Authors; This study is interesting. But is not presented properly. There are many issues in the manuscript and need improvement, however, major comments are given for revisions.
Dear Authors; Corrosion Inhibition of Rumex vesicarius Mediated Chitosan-AgNPs Composite for C1018 CS in CO2-Saturated 3.5% NaCl Medium under Static and Hydrodynamic Conditions. This study is interesting. But is not presented properly. There are many issues in the manuscript and need improvement, however, major comments are given for revisions.
1. Add few more lines of methodology in abstract.
2. Add key recommendation at the end of abstract.
3. Formatting issues in introduction (e.g. line 46-55).
4. Citation styles needs to consistent (line 51).
5. Avoid using pronouns (e.g. I, We). Use proper scientific language.
6. Add relevant citation for this statement/ methods: The results obtained from the LPR technique is consistent with other electrochemical methods. (line 282-283)
7. There is need to concise discussion of results (e.g. effect of immersion time).
8. Add few more citation in all sections of results discussion (e.g. surface analysis).
9. Tables need to be formatting (e.g. table 4, 6, 9).
10. Only 13 references (out of 41) of last 5-years are used in the study. Add latest relevant citations to support your results.
11. Replace figure 1 with software generated figure or improved one.
Reviewer 2 Report
The article presents the effectiveness in using a sustainable solution for reducing the corrosion of carbon steel in CO2-Saturated 3.5% NaCl 3 Medium. The evaluation of the corrosion testing results indicated an interesting improvement on the corrosion inhibition, which is evidenced by the polarization resistance values with the CI concentration.

Reviewer 3 Report
The paper contains significant information adequate to justify publication.
The English language is of good quality. Very little mistakes are found in the text. I have introduced suggestions and corrections (please refer to the attached reviewed PDF manuscript file containing all my comments and suggestions):
- Perhaps: ‘perform’ (line 52),
- 'synthesis' is a noun and cannot be used with 'to'. Perhaps: 'to synthesize' (line 88)
- Perhaps: 'deacetylation' (line 96)
- Chemical composition of the carbon steel is declared in the text, but is not given (lines 99, 100)
- Perhaps: Figure 8 (line 377) ?!
- Fig. 8b (line 382 and line 384) ?!
- All of the Figures 1-13 are misplaced. Figures have covered their captions, and has made it very difficult to read the captions. Technical editing has been done improperly. Despite of this, I have managed to read the Figure captions. Unfortunately, Figures 11c and 12c are missing. Figure 13 has almost completely covered Figure 12 c – erroneously marked as Figure 12a, thus having two Figures 12a. This has made it almost impossible to review the Figures, particularly Figures 11-13.
