Methodology description
Criteria Feedback
- Research question is clearly articulated within a specific context of baking chemistry, gas evolution and Arrhenius theory
- Hypothesis is well justified by kinetic molecular theory and the Arrhenius equation
- Materials list is comprehensive and procedure is detailed and sequential, allowing reproduction with few ambiguities
- Purity and batch number of chemicals are not specified, limiting full reproducibility
- Stirring consistency and flask sealing method are not addressed
- ‘Quickly close the flask’ is not defined with a target time
- Temperature and duration for dissolving powder are not specified

Data processing quality
Criteria Feedback
- Raw and processed data are well organised in labelled tables with units and clear averages
- Graphs include axes, units, best-fit lines and statistical parameters, supporting clear and precise communication
- Consideration of uncertainties is evident with absolute and percentage values and error bars plotted
- Unit conversions contain typos and inaccuracies (e.g. ‘Pa/c’ instead of ‘Pa/s’)
- Uncertainty propagation is simplistic (max–min/2) and omits sensor’s systematic error
- No R² or residual analysis is provided to substantiate linear fits
- Differential steps in deriving rate expression are not fully explicit
