At 900 k the following reaction has kp=0.345: 2so2(g)+o2(g)ââ2so3(g) in an equilibrium mixture the partial pressures of so2 and o2 are 0.125 atm and 0.470 atm , respectively.
what is the equilibrium partial pressure of so3 in the mixture?

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

                      The expression for equilibrium constant for this reaction will be,

Now put all the given values in this expression, we get :

Thus the equilibrium partial pressure of in the mixture is

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
