Why does the equilibrium of a system shift when the pressure is increased?
Answers
Explanation:
According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. ... For example, if the temperature is increased for an endothermic reaction, essentially a reactant is being added, so the equilibrium shifts toward products.
A reaction is said to be in equilibrium when the rate of forward reaction and rate of backward reaction are equal. This principle is called Le-Chatelier's principle. Such reactions are also reversible reactions. Since equilibrium is the most stable state of a system, when we increase pressure on either side of the system, the molecules will shift towards the other side to maintain the equilibrium state.
This happens because a system in equilibrium always tends to maintain its state of equilibrium in case of a reversible reaction.
