Arrhenius rate ratio
For a reaction in a environmental chemistry case study, \(E_a=69\,\text{kJ mol}^{-1}\), \(T_1=310\,\text{K}\), and \(T_2=335\,\text{K}\). Calculate \(\ln(k_2/k_1)\). Use the labelled diagram, graph, or data table before calculating. Enter the answer and choose the interpretation that matches the HL chemistry evidence.
Worked practice: chemistry evidence and answer
Use the chemical evidence first, then enter the result and interpretation that match it.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
