The student clearly stated the independent variable, which was the concentration of sulfuric acid, and the dependent variable, the rate of esterification measured by the volume of methyl butanoate produced over time. However, the student did not adequately describe the method of analysis in the research question, lacking specifics on how the rate of esterification would be measured. Additionally, the background theory section was insufficient, as it did not cover key concepts related to the research question. The student provided a detailed explanation of the methodology, including controlled variables, safety issues, and environmental considerations, ensuring the investigation would be reproduced without irrelevant information.
