Question: In a closed system, if a reactant is removed from the equilibrium mixture, what will happen? (2019)

Options:

Correct Answer: Shift to the left

Exam Year: 2019

Solution:

Removing a reactant will shift the equilibrium to the left to produce more reactants, according to Le Chatelier\'s principle.

In a closed system, if a reactant is removed from the equilibrium mixture, what will happen? (2019)

Step 1: Understand that a closed system means no substances can enter or leave the system.
Step 2: Recognize that equilibrium is a state where the forward and reverse reactions occur at the same rate.
Step 3: Identify that a reactant is a substance that is used up in the reaction to form products.
Step 4: When a reactant is removed, there are fewer reactants available for the reaction.
Step 5: According to Le Chatelier's principle, the system will try to counteract this change.
Step 6: To counteract the removal of the reactant, the equilibrium will shift to the left, which means it will produce more reactants.
Step 7: This shift helps restore balance in the system.

Le Chatelier's Principle – This principle states that if a system at equilibrium is disturbed, the system will adjust to counteract the disturbance and restore a new equilibrium.
