Question

Which information can be obtained from Le Chatelier's principle?

• A. Shift in equilibrium position on changing $P,T$ and concentration
• B. Dissociation constant of a weak acid
• C. Energy change in a reaction
• D. Equilibrium constant of a chemical reaction

Answer 1

The correct option is A Shift in equilibrium position on changing $P,T$ and concentration

Le Chtelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to re-establish equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change.

Hence, option A is correct.
