so i have a table that tell me whether the its a strong/ weak acid/ base
but how do i use it to determine whether the equation will favor left or right of the equilibrium?

  • chemistry -

    If the acid/base has a Kb or Kb then it is a weak acid/base. If it has no Ka or Kb it is a strong acid/base.
    Which way the reaction is favored is Le Chatelier's principle. Simply stated it says that a system at equilibrium will try to undo what we do to it. What does that mean.
    A + B <==> C + D + heat. At equilibrium.
    If we add A, the reaction will try to undo that. How? It will use up A. How so? By reacting with B to form more C and D (in chemical parlance that is shifting to the to right). Suppose we change T from 100 C to 500 C. Adding heat means the reaction will try to cool it to use up the extra heat. How can it do that. By moving the reaction to the left USES heat. (Moving to the right produces more heat and you don't want to do that if you are trying to cool it.) That's the picture.
