Question: Which of the following changes will NOT affect the position of equilibrium for the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g)?

Options:

Correct Answer: Adding a catalyst

Solution:

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 for the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g)?

Which of the following changes will NOT affect the position of equilibrium for the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g)?

Correct Answer: A catalyst

Step 1: Understand what equilibrium means in a chemical reaction. It is the point where the rate of the forward reaction equals the rate of the reverse reaction.
Step 2: Identify the reaction given: 2SO2(g) + O2(g) ⇌ 2SO3(g). This means sulfur dioxide (SO2) and oxygen (O2) can turn into sulfur trioxide (SO3) and vice versa.
Step 3: Recognize that changes in concentration, temperature, or pressure can affect the position of equilibrium.
Step 4: Learn what a catalyst does. A catalyst is a substance that speeds up a reaction without being consumed in the process.
Step 5: Realize that a catalyst increases the speed of both the forward and reverse reactions equally.
Step 6: Conclude that since a catalyst does not change the ratio of products to reactants at equilibrium, it does NOT affect the position of equilibrium.
