Use equilibrium constants for gases and solutions

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. 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.
