Question: Which of the following changes will NOT affect the position of equilibrium in a chemical reaction?

Options:

Correct Answer: Adding a catalyst

Solution:

Adding a catalyst speeds up the rate of both the forward and reverse reactions equally, thus it does not affect the position of equilibrium.

Which of the following changes will NOT affect the position of equilibrium in a chemical reaction?

Which of the following changes will NOT affect the position of equilibrium in a chemical reaction?

Step 1: Understand what equilibrium means in a chemical reaction. It is the point where the forward and reverse reactions happen at the same rate.
Step 2: Know that changing concentration, temperature, or pressure can shift the position of equilibrium.
Step 3: Learn that a catalyst is a substance that speeds up a reaction without being consumed.
Step 4: Realize that a catalyst affects both the forward and reverse reactions equally.
Step 5: Conclude that since a catalyst does not change the rates of the reactions differently, it does not change the position of equilibrium.
