Use equilibrium constants for gases and solutions

Paper 1, Paper 2 5 marks Difficulty 5

Convert Kp to Kc for gas equilibrium

A gas equilibrium in a IA data review session has \(K_p=6\) and \(\Delta n=1\). Using \(RT=24.8\), calculate \(K_c\) from \(K_p=K_c(RT)^{\Delta n}\). 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.
