4 x 1 hour lessons

This module focuses on chemical equilibrium in both qualitative and quantitative terms. You'll begin by revising the dynamic nature of equilibrium and the effect of changes in concentration, pressure, and temperature, as explained by Le Chatelier’s principle.

You’ll then move on to equilibrium calculations involving the equilibrium constant, Kc​, including how to construct expressions, calculate equilibrium concentrations, and interpret the magnitude of Kc​ in terms of position of equilibrium. You'll extend this to Kp​, the equilibrium constant for gaseous systems, and practise performing calculations using partial pressures.

​

By the end of this module, you’ll be able to:

• Explain the dynamic nature of equilibrium

• Predict the effect of changing conditions using Le Chatelier’s principle

• Write expressions for KcK_cKc​ and KpK_pKp​

• Calculate KcK_cKc​ and KpK_pKp​ from experimental data

• Interpret the significance of the values of equilibrium constants
