Restoring Balance LeChâtelier’s Principle and Equilibrium Introduction Chemical equilibrium is a true balancing act. What happens when the balance is disturbed? The purpose of this lab is to observe the effects of concentration and temperature on equilibrium and to visualize how balance can be restored based on LeChâtelier’s Principle. Background Not all chemical reactions proceed to completion‚ that is‚ to give 100% yield of products. In fact‚ most chemical reactions are reversible
