Questions & Step-by-Step Solutions

In the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what is the effect of increasing the pressure on the equilibrium?
  • Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
  • Step 2: Count the number of gas molecules on each side of the reaction.
  • Step 3: On the left side (reactants), there are 2 moles of SO2 and 1 mole of O2, totaling 3 moles of gas.
  • Step 4: On the right side (products), there are 2 moles of SO3, totaling 2 moles of gas.
  • Step 5: Compare the number of moles of gas on both sides: 3 moles on the left and 2 moles on the right.
  • Step 6: Understand that increasing pressure in a reaction shifts the equilibrium towards the side with fewer moles of gas.
  • Step 7: Since the right side has fewer moles (2 moles of SO3), the equilibrium will shift to the right.
