Question

Le Chatelier's Principle states that if a chemical system at experiences a change in concentration, , volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established. Consider the following equilibrium: H2CO3 (aq) H2O (I) + 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:

Explanation / Answer

Q#1 Equillibrium and Temperature

The last option removing CO2 by adding CaCl2 will favour the equillibrium to right and all other options to left
