Syllabus-aligned Chemistry skill. Draft skills remain inactive until production seed coverage is added.

Paper 1, Paper 2 5 marks Difficulty 4

Use a rate expression

A rate law in a Auckland reaction-rate practical is \(\text{rate}=k[A][B]\), with \(k=0.5\), \([A]=0.24\), and \([B]=0.32\). Calculate the rate. Use the labelled diagram, graph, or data table before calculating. Enter the answer and choose the interpretation that matches the HL chemistry evidence.
