At 930 K, Kp = 0.30 for the following reaction.
2 SO2(g) + O2(g)=>2 SO3(g)
Calculate the equilibrium partial pressures of SO2, O2, and SO3 produced from an initial mixture in which the partial pressures of SO2 and O2 = 0.51 atm and the partial pressure of SO3 = 0 (exactly).
partial pressure of SO2

partial pressure of O2

partial pressure of SO3

1. .........2SO2(g) + O2(g)=> 2SO3(g)
I.........0.51.....0.51......0
C..........-2x......-x......2x
E.......0.51-2x...0.51-x....2x

Substitute the E line into Kp expression and solve for x, then evaluate the other numbers.
