Derive and use rate expressions

Paper 1, Paper 2 5 marks Difficulty 5

Rate constant unit reasoning

A second-order rate law in a industrial equilibrium audit uses rate units \(\text{mol dm}^{-3}\text{s}^{-1}\). State the appropriate units for \(k\). 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.
