What will happen to the equilibrium If the volume of the container is reduced by 50% at constant temperature? The equilibrium constant will increase. The equilibrium constant will decrease. The reverse reaction will proceed to re-establish equilibrium. The forward reaction will proceed to re-establish equilibrium. Neither the forward nor the reverse reaction will proceed to re-establish equilibrium QUESTIONS Which of the following is a basic solution at 25°C pH = 4.5 Save All Ar o Click Save and Submit to save and submit.

Answer 1

SOLUTION ka The given problem is an application Le Chatelier's Principles what which states that the position of equilibrium will move in such a way as to counteract the change applied. We know that pressure and volume are inversely related Thus when volume of an equilibrium system is reduced to 50%, pressure of the system will be increased by same factor. To counteract this change, equilibrium position will move towards product or reactant side depending on which side. has lesser number of moles. since lower the number of moles, lower the pressure The given equation, (CH₂).COH (9) - (CH3 C CH₂ (9) + H₂O has lese mde on reactant side so equilibrium will shift to reactant side. Thus the correct option is & The reverse reaction will proceed to re-establish equilibrium.

Hope that this solution will help you.
