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

Options:

Correct Answer: Shifts to the right

Solution:

Increasing the concentration of a reactant shifts the equilibrium position to the right, favoring the formation of products (SO3).

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what is the effect of increasing the concentration of SO2?

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what is the effect of increasing the concentration of SO2?

Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
Step 2: Recognize that SO2 is a reactant in this reaction.
Step 3: Understand that increasing the concentration of a reactant (SO2) means there are more SO2 molecules available.
Step 4: Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
Step 5: Since we increased the concentration of SO2, the equilibrium will shift to the right to use up the extra SO2.
Step 6: This shift to the right favors the formation of the product, which is 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.
