Which of the following changes will increase the amount of CaCO3(s) in the reaction
CaCO3(s)⇌CaO(s)+CO2(g)?
Removal of CaO(s)
Removal of CO2(g)
Temperature is lowered
Volume of container is decreased
The decomposition of CaCO3 will be endothermic and hence lowering the temperature will move the reaction in backward direction.
