Equilirbium question

  1. Feb 11, 2007 #1
    1. The problem statement, all variables and given/known data
    refer to attachment please. I've tried many times but my answer seems to be wrong.

    2. Relevant equations
    none needed.

    3. The attempt at a solution
    I looked at what the equilibrium would do to relieve the stress onto the system but my answer seems to be wrong.

    *refer to the attachment

    thanks in advance

    Please show one's work for each of 5 questions.

    What does increasing pressure do for the formation of ammonia?

    1. the equilibrium will not shift, because while the total pressure will raise, the concentrations will still be the same (the same amount of mols of each gas per volume) since the volume did not change

    2. it will shift to the left. there are 4 mols of gas on the left, and 2 mols of gas on the right side. when you lower the pressure, according to la chatelier's principle, the equilibrium will tend to conteract (ie, the pressure will try to go back up). in order for the pressure to go back up, the equilibrium shifts to the left because there are more mol of gas on the left

    3. false, because when you add water, the concentrations will change, which effects the equilibrium

    4. false, from, la chatelier's principle, in order to counteract the increase in H2 concentration, more H2 will react, meaning more I2 will react, meaning hte equilibrium shifts to the right

    5. adding heat will make it shift to the left because thats how the extra heat would be counteracted. if it is shifting to the left, is the equilibrium constant be higher or lower than Kc?
