I don’t understand your question
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.
(b) boiling of water is an endothermic process.
A response that is chemical in nature and is characterized with the aid of the release of power in the shape of warmth or light is referred to as an exothermic response. Matching a mild using a matchstick is one example of this kind of reaction where the discharge is inside the shape of each warmness and light.
Endothermic reactions are chemical reactions wherein the reactants soak up warmness electricity from the environment to shape products. those reactions decrease the temperature of their surrounding place, thereby growing a cooling impact.
