Connect Gibbs energy with equilibrium constants

Paper 1, Paper 2 5 marks Difficulty 4

Gibbs energy to ln K

For a reaction in a IA data review session, \(\Delta G^\circ=-12\,\text{kJ mol}^{-1}\) at \(298\,\text{K}\). Calculate \(\ln K\). 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.
