4 x 1 hour lessons

This module introduces dynamic equilibrium and extends into equilibrium constants and industrial applications. You’ll learn to calculate and interpret Kc and Kp, and apply Le Chatelier’s Principle to explain how changing conditions affect chemical equilibria in both qualitative and quantitative terms.

By the end of this module you will be able to: • describe the characteristics of dynamic equilibrium • apply Le Chatelier’s Principle to changes in concentration, pressure, and temperature • write expressions for Kc and Kp and calculate their values • calculate equilibrium concentrations using Kc and Kp • interpret the significance of large/small K values • describe how catalysts affect the rate but not position of equilibrium • explain compromises made in industrial equilibrium processes
