The student clearly stated the independent variable as temperature and the dependent variable as the reaction rate, linking the two through the change in pressure related to CO2 production. The posed research question effectively outlines the method of analysis, detailing how the reaction rate will be determined from pressure changes, supported by relevant scientific principles. A comprehensive background theory is provided, explaining the impact of temperature on reaction rates and incorporating key concepts like the ideal gas law. The methodology is well described, with clear explanations of measurement techniques and a systematic approach to trials, although additional details on controlled variables would enhance clarity. Safety, ethical, and environmental considerations are thoroughly addressed, ensuring the investigation adheres to necessary protocols.
