Question

the reaction below shows a system in equilibrium how would an increase in the concentration of chemicals affect this reaction?

Answer 1

Option B. The equilibrium of the reaction would shift to the right.

Step-by-step explanation:

According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.

Now, let us answer the question above.

From the question given above, the equation is:

A + B <===> C + D

Increasing the concentration of A will shift the equilibrium position to the right.

This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.
