Questions & Step-by-Step Solutions

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what will happen if the pressure is increased?
  • Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
  • Step 2: Count the number of gas moles on each side of the reaction.
  • Step 3: On the left side (reactants), there are 3 moles of gas (2 from SO2 and 1 from O2).
  • Step 4: On the right side (products), there are 2 moles of gas (from SO3).
  • Step 5: Understand that increasing pressure in a reaction favors the side with fewer moles of gas.
  • Step 6: Since the right side has fewer moles (2 moles of SO3), the equilibrium will shift to the right.
  • Step 7: This means more SO3 will be produced when pressure is increased.
