Paper 1, Paper 2 5 marks Difficulty 5

Compare Q with K

In a IA data review session, a reaction mixture has \(Q=0.42\) and \(K=1.80\). Predict the direction of change before equilibrium is reached. Use the labelled diagram, graph, equation, or table before answering. 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.
