Demonstrate the power of balance in a reversible chemical reaction by showing how chemical equilibrium represents a true chemical balancing act and thus responds dramatically to anything that might upset that balance.
This chemical demonstration allows students to observe the effect of concentration and temperature on the position of equilibrium for an endothermic chemical reaction, infer how a chemical system responds to changes in order to restore chemical equilibrium, and thus to formulate their own version of LeChâtelier’s Principle, and visualize the dynamic nature of chemical equilibrium.
