Question: For the equilibrium reaction A ⇌ B, if the concentration of B is increased, what will be the effect on the equilibrium? (2023)

Options:

Correct Answer: Shift to the left

Exam Year: 2023

Solution:

Increasing the concentration of B will shift the equilibrium to the left to produce more A, according to Le Chatelier\'s principle.

For the equilibrium reaction A ⇌ B, if the concentration of B is increased, what will be the effect on the equilibrium? (2023)

Step 1: Understand that A and B are in equilibrium, meaning they can convert into each other.
Step 2: Recognize that increasing the concentration of B means there is more B present in the reaction.
Step 3: Apply 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: Since we increased B, the system will try to reduce the amount of B by shifting the equilibrium to the left.
Step 5: Shifting the equilibrium to the left means that more A will be produced from B.

Le Chatelier's Principle – This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
