The student provides a focused and detailed description of the main topic, clearly explaining the investigation of the rate of reaction versus the mass of heterogeneous catalyst. Additionally, the background information given is relevant and well-organized, making it easier to understand the chemical concepts. The chemistry of the experiment is explained clearly, allowing the reader to fully comprehend the process without the need for rereading. The methodology of the investigation is highly appropriate to the topic, including steps to assure the relevancy and validity of the obtained results. However, the dependent variable in the methodology should be rephrased to better align with the research question.
