Question: In the equilibrium reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), if SO2 is added, what will be the effect on the equilibrium?

Options:

Correct Answer: Shift to the right

Solution:

Adding SO2 will shift the equilibrium to the right to produce more SO3, according to Le Chatelier\'s principle.

In the equilibrium reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), if SO2 is added, what will be the effect on the equilibrium?

Step 1: Understand that the reaction involves sulfur dioxide (SO2), oxygen (O2), and sulfur trioxide (SO3).
Step 2: Recognize that the reaction can go in both directions: from left to right (producing SO3) and from right to left (producing SO2 and O2).
Step 3: Know that equilibrium means the rates of the forward and reverse reactions are equal, and the concentrations of the reactants and products remain constant.
Step 4: When you add more SO2 to the system, you increase the concentration of one of the reactants.
Step 5: According to Le Chatelier's principle, if you change the concentration of a reactant or product, the equilibrium will shift to counteract that change.
Step 6: Since you added SO2, the equilibrium will shift to the right to use up the extra SO2 and produce more SO3.
Step 7: The result is an increase in the concentration of SO3.

Le Chatelier's Principle – When a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance.
