This diagram covers Comparing Reaction Graphs within Factors Affecting Rate for GCSE Chemistry. Revise Factors Affecting Rate in Rates of Reaction for GCSE Chemistry with 24 exam-style questions and 18 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 4 of 13 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
📊 Comparing Reaction Graphs
When you change rate factors:
- Faster reaction: Steeper initial curve, reaches plateau sooner
- Same amount of limiting reactant: Same final amount of product (same plateau height)
- More reactant: Higher plateau (more product made)
| Higher temperature | Higher concentration |
|---|---|
| Steeper curve, same final volume | Steeper curve, same final volume (if same moles) |
