Answer 1

Answer:

The concentrations change to maintain the original value of K.

Explanation:

When the concentration of a system is changed, the system adjusts in order to preserve the original value of the equilibrium constant K.

• The equilibrium constant is a constant at a given temperature and it is temperature dependent in nature.

According to Le Chatelier's principle;

• If any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change.
• Stress due to any of pressure, temperature and concentration changes displaces the equilibrium.
