The student clearly stated the independent variable (temperature) and the dependent variable (rate constant of the esterification reaction) in the research question. They described the method of analysis, specifying that the rate constant would be measured through acid-base titration at set intervals. The background theory was well-articulated, covering the esterification process and relevant concepts, such as the Arrhenius equation and collision theory. However, the student did not provide a clear explanation of the techniques used to measure the variables, which needed improvement. The methodology was comprehensive and detailed, allowing for reproducibility and clarity, while adequately addressing safety and environmental concerns. Ethical issues, however, were not explicitly mentioned, which was a gap that should have been rectified.
