Which of the following changes will NOT affect the position of equilibrium in a closed system?
Adding a catalyst
Changing the concentration of reactants
Changing the pressure
Changing the temperature
A catalyst speeds up the rate of both the forward and reverse reactions equally, thus it does not change the position of equilibrium.

Q
Q: Which of the following changes will NOT affect the position of equilibrium in a closed system?
Solution: A catalyst speeds up the rate of both the forward and reverse reactions equally, thus it does not change the position of equilibrium.
Steps: 5
Step 1: Understand what equilibrium means in a closed system. It is the point where the forward and reverse reactions occur at the same rate.
Step 2: Identify what factors can change the position of equilibrium. These include changes in concentration, temperature, and pressure.
Step 3: Learn about catalysts. A catalyst is a substance that speeds up a reaction without being consumed in the process.
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 relative to each other, it does not change the position of equilibrium.
