• State le Chatelier’s principle. Week 26 • Explain that a dynamic equilibrium exists when the rate of the forward reaction is equal to the rate of the reverse reaction. • State le Chatelier’s principle. Apply le Chatelier’s principle to deduce qualitatively the effect of a change in concentration or pressure, on a homogeneous system in equilibrium. © Pearson Education Ltd 2008 This document may have been altered from the original
