Question: In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if SO2 is removed from the system?

Options:

Correct Answer: Shift to the left

Solution:

Removing SO2 will shift the equilibrium to the left to produce more SO2, according to Le Chatelier\'s principle.

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if SO2 is removed from the system?

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: Know 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: When SO2 is removed from the system, there is less SO2 available for the reaction.
Step 5: To counteract the removal of SO2, the equilibrium will shift to the left, meaning the reaction will produce more SO2 from SO3.
Step 6: As a result, the amounts of SO2 will increase until a new equilibrium is reached.

Le Chatelier's Principle – When a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance.
Chemical Equilibrium – The state in which the concentrations of reactants and products remain constant over time.
