• A) The pressures of SO₃ and NO decrease;the pressures of SO₂ and NO₂ increase.
• B) The pressures of SO₃ and NO increase;the pressures of SO₂ and NO₂ decrease.
• C) The pressures of SO₃ and SO₂ decrease;the pressures of NO and NO₂ increase.
• D) The pressures of SO₃ and SO₂ increase;the pressures of NO and NO₂ decrease.
• E) Equal numbers of particles exist on both sides of the equation;no reaction will occur.
