Question: For the reaction A + B ⇌ C + D, if the concentration of C is decreased, what will be the effect on the equilibrium?

Options:

Correct Answer: Shift to the right

Solution:

Decreasing the concentration of C will shift the equilibrium to the right to produce more C and D.

For the reaction A + B ⇌ C + D, if the concentration of C is decreased, what will be the effect on the equilibrium?

For the reaction A + B ⇌ C + D, if the concentration of C is decreased, what will be the effect on the equilibrium?

Step 1: Understand that the reaction A + B ⇌ C + D is in equilibrium, meaning the forward and reverse reactions are happening at the same rate.
Step 2: Recognize that decreasing the concentration of C means there is less of C available in the reaction.
Step 3: According to Le Chatelier's principle, if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Since the concentration of C is decreased, the system will try to increase it back to restore equilibrium.
Step 5: To produce more C, the reaction will shift to the right, which means more A and B will react to form more C and D.

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.
