Which action will increase the rate of this reaction?

Question

Calcium carbonate (CaCO₃) breaks down at high temperatures according to the equation shown below. Assume the reaction takes place in a sealed reaction vessel.

CaCO₃ —> CaO + CO₂

Answer 1

According to Le Chateliers principle - Le Chatelier's principle (also known as "Chatelier's principle" or "The Equilibrium Law") states that when a system experiences a disturbance (such as concentration, temperature, or pressure changes), it will respond to restore a new equilibrium state. Removal of product (CO2) and addition of heat will move the reaction forward. Also, more entropy is caused on product side because a gas is formed, removal of CO2 will reduce entropy (disorder).
