Question: In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if the concentration of SO3 is decreased?

Options:

Correct Answer: Shifts equilibrium to the right

Solution:

Decreasing the concentration of SO3 will shift the equilibrium to the right to produce more SO3, according to Le Chatelier\'s Principle.

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if the concentration of SO3 is decreased?

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if the concentration of SO3 is decreased?

Step 1: Understand that the reaction involves sulfur dioxide (SO2), oxygen (O2), and sulfur trioxide (SO3).
Step 2: Recognize that the reaction can reach a state of balance called equilibrium, where the amounts of reactants and products remain constant.
Step 3: Identify that Le Chatelier's Principle states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Note that decreasing the concentration of SO3 means there is less SO3 present in the reaction.
Step 5: According to Le Chatelier's Principle, the system will try to increase the concentration of SO3 to restore balance.
Step 6: To produce more SO3, the reaction will shift to the right, which means more SO2 and O2 will react to form SO3.

Le Chatelier's Principle – When a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.
