The Equilibrium Constant,K_p,for the Reaction Below Is 0

The equilibrium constant,K_p,for the reaction below is 0.24 at 1500°C.
SO₃(g) + NO(g) ⇌ SO₂(g) + NO₂(g)
If 0.30 atm of sulfur trioxide,0.15 atm of nitrogen monoxide,0.55 atm of sulfur dioxide,and 0.030 atm of nitrogen dioxide are mixed,what changes in pressure will occur?

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.
