The Gas-Phase Equilibrium of the Oxidation of Sulfur Dioxide, Shown $\degree$

The gas-phase equilibrium of the oxidation of sulfur dioxide, shown here, has an equilibrium constant, K_p, value of 4.17 * 10² at 200 $\degree$ C. If a closed vessel was filled with sulfur trioxide and the initial pressure of SO₃ was 0.033 atm at 200 $\degree$ C, what would be the final partial pressure of SO₃?
2SO₂(g) + O₂(g) $\leftrightarrows$ 2SO₃(g)

A) more than 0.033 atm
B) less than 0.033 atm
C) 0.033 atm exactly
D) there is no way to tell
