Answer: d. Remove one-half of the initial CaCO3.
Explanation: Le Chatelier's principle states that changes on the temperature, pressure, concentration and volume of a system will affect the reaction in an observable way. So in the reaction above:
A decrease in temperature will shift the equilibrium to the left because the reaction is exothermic, which means heat is released during the reaction. In other words, when you decrease temperature of a system, the equilibrium is towards the exothermic reaction;
A change in volume or pressure, will result in a production of more or less moles of gas. A increase in volume or in the partial pressure of CO2, the side which produces more moles of gas will be favored. In the equilibrium above, the shift will be to the left.
A change in concentration will tip the equilibrium towards the change: in this system, removing the product will shift the equilibrium towards the production of more CaCO3 to return to the equilibrium.
So, the correct answer is D. Remove one-half of the initial CaCO3.
The changes that will form more CaCO3 is to Remove one-half of the initial CaCO3.
Le Châtelier's principle explain that dynamic equilibrium is been disturbed with alterations of conditions, which changes the position of equilibrium and shifts to counteract the change.
In the given equation, we can Remove one-half of the initial CaCO3 produced this will change the system and more CaCO3 will be produced.
Therefore, option D is correct.
