Questions & Step-by-Step Solutions

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.
