Question

Explain Le-chatelier's principle.

Answer 1

  Le-chatelier's principle states that if a constraint such as change in temperature , pressure , concentration is added to the system in equilibrium then equilibrium shifts ion such the way that in order to nullify the effect of the added constraint 

Answer 2

Answer:

In response to a change in temperature, concentration, volume, or pressure, it can be used to predict the path of a chemical reaction. Le Chatelier's principle can be used to predict how a system will react to a change in equilibrium, but it cannot (at the molecular level) explain why the system would react the way it does.

Explanation:

The equilibrium law, commonly known as Le Chatelier's principles, is used to predict how certain changes would affect a system in chemical equilibrium (such as the change in temperature or pressure). The French scientist Henry Louis Le Chatelier is acknowledged by the principle's name.

According to Le Chatelier, equilibrium modifies the forward and backward reactions to accommodate changes that influence the equilibrium circumstances.

For example: 2SO₂(g) + O₂(g) ⇋ 2SO₃(g)

• Equilibrium will change in favor of a decrease in reactant concentration if the concentration of the reactant increases.

• Equilibrium will move toward an increase in reactant concentration if the concentration of the reactant decreases.

• The equilibrium of the reaction shifts to a rise in sulfur trioxide concentration if the product decreases.

• The equilibrium of the reaction shifts to reduce the concentration of sulfur trioxide if the product increases.

Hence,  Le-chatelier's principle is explained above.
