Le Chatelier

  1. Mar 16, 2012 #1
    1. The problem statement, all variables and given/known data

    What factors will change when additional B(g) is added to the following system at equilibrium.
    Overall Reaction: A(g) + B(g) [itex]\Leftrightarrow[/itex](g)
    3. The attempt at a solution

    I said decreases, [A] decreases, [C] increases, and equilibrium will shift to the right....but i got it wrong...why and what would it be then?

    If additional B is added, the last thing I would posit is that B would decrease. Everything else you have seems correct.

    then why would A decrease.....

    When more product is made, it requires A to do so. A decreases. I believe your actual difficulty is one of initial conditions. You've assumed that the initial conditions are at a point after the addition of extra B and before the new mixture comes to equilibrium but the question assumes it is before B is added.
    It appears that you have a good grasp of the concept so relax and don't debate semantics. You'll get nowhere with that.
