Given the following reaction:

heat + CaCO3(s) <----> CaO(s) + CO2(g)

a. In which direction, if any, will the equilibrium shift when the pressure of CO2 is increased?

b. In which direction, if any, will the equilibrium shift if the temperature is decreased?

c. In which direction, if any, will the equilibrium shift if the amount of CaCO3 is increased?

Answer #1

a. Increasing the pressure of CO2 is the same as increasing its concentration. The system will try to reestablish equilibrium by consuming some CO2, shifting the equilibrium to the reactants (left).

b. Temperature is your source of heat within the system. When the temperature is decreased the heat is also decreased. The system will try to reestablish equilibrium by shifting to the reactants (left).

c.if caco3 is increased , the equilibrium shift to right.
