Question: In a reversible reaction at equilibrium, what happens if the concentration of a reactant is increased? (2023)

Options:

Correct Answer: The equilibrium shifts to the right

Exam Year: 2023

Solution:

According to Le Chatelier\'s principle, increasing the concentration of a reactant will shift the equilibrium to the right to produce more products.

In a reversible reaction at equilibrium, what happens if the concentration of a reactant is increased? (2023)

Step 1: Understand that a reversible reaction can go in both directions: from reactants to products and from products back to reactants.
Step 2: Know that equilibrium is the point where the rate of the forward reaction equals the rate of the reverse reaction.
Step 3: Recognize Le Chatelier's principle, which states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: When the concentration of a reactant is increased, the system will try to reduce that concentration.
Step 5: To reduce the concentration of the added reactant, the equilibrium will shift to the right, favoring the formation of more products.

Le Chatelier's Principle – This principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.
