What happens when you add more reactant to a reaction using Le Chatlier's principal? How about if we remove reactant, add/remove product?

  • Adding a reactant: reactant increases, more products are formed, SHIFT RIGHT 

  • Remove reactant: more reactant will form SHIFT LEFT 

  • Adding product: more reactant will form SHIFT LEFT 

  • Removing product: decrease reactant and more product will form SHIFT RIGHT 

  • Pretend heat is a product
