Shown below is the chemical equation for the thermal decomposition of calcium carbonate.

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

H°rxn = 175 kJ

How will the amount (not concentration) of CaCO3(s) change with the following stresses?

CO2(g) is removed?
Decrease, Increase or No Change

CaO(s) is added?
Decrease, Increase or No Change

The temperature is increased.
Decrease, Increase or No Change

The volumes of the container is decreased.
Decrease, Increase or No Change
