Question

Equilibrium Problems
Can someone check my work on these problems please?

Answer 1

Sulfur trioxide decomposes at high temperature in a sealed container:
\[2 SO _{3}(g) \leftarrow \rightarrow 2SO _{2}(g) +O _{2}(g)\]
Initially the vessel is charged at 1000K with SO3 at a partial pressure of .500 atm. At equilibrium the SO3 partial pressure is .200 atm. Calculate the value of Kp at 1000K
