For the equation, SO2(g) + 1/2 O2(g)> SO3(g) Kp=9.5
EQUAL partial pressures of SO2 and O2 are placed in an empty reaction vessel and heated to 600 degrees celsius. Assuming that 62% of the SO2 partial pressure has reacting to give S03, calculate the partial pressure of S03 at equilibrium.
So far, I did:
R SO2 + 1/2 O2 > SO3
I X X 0
C .62X .31X. +.62X
E X.62X X.31X .62X
And 9.5=(.62X)/(X.62X)(X.31X)
But I'm not sure if I set this up right or how to solve for X. I am not getting the correct answer. Please help!! Thank you!!!

kellie,
Sorry I forgot to add that the last value, (X.31X) is raised to the 1/2 power
