The student provides a focused and detailed description of the main topic, clearly stating and explaining the topic of investigating the effect of sulphuric acid concentration on the rate of reaction and determining its enthalpy change. The student also provides relevant and focused background information, although the section on wastewater treatment could be shortened as it is not directly related to the topic. The chemistry of the experiment is well explained, including the reactants, products, rate of reaction, and concentration. The methodology of the investigation is highly appropriate to the topic, conducting two experiments using a calorimeter and measuring the time needed for the reaction to reach its end at different concentrations of H2SO4. The student also shows full awareness of safety hazards and environmental issues. However, they should have mentioned any ethical concerns if applicable.
