Question

What is the effect of increasing the concentration of a reactant in a system at equilibrium?
Options
A No effect
B Shifts the equilibrium to the product side
Correct Answer
C Shifts the equilibrium to the reactant side
D Increases the activation energy
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to Le Chatelier's principle, if a system at equilibrium is disturbed by increasing the concentration of a reactant, the equilibrium will shift to consume that reactant, favoring the forward reaction and thus shifting to the product side.

Hint

The system tries to counteract the change by using up the added reactant.
