Consider the following equilibrium:
H2CO3 (aq) ↔ H2O (l) + CO2 (g)

Which direction will the equilibrium shift (left or right) if we:

Increase the pressure by decreasing the volume of the system:

Increase the pressure by adding Argon to the system:

Addition of NaOH (aq) to the system:

Addition of CaCl2 (aq) to the system:

  • Chemistry -

    Adding pressure makes the reaction shift to the side with the fewer gas mols. Adding Ar has no effect.

    For the others, the system will shift to undo what we've done to it. If we add NaOH, that reacts with H2CO3 to form the salt + H2O thus decreasing H2CO3. So the reaction will shift to the left in order to try and increase the lost H2CO3.

  • Chemistry -

    1) No Change
    2) Left
    3) Left
    4) Right
