How to write solubility equilibrium and solubility-product constant expression?

Write the expression for the equilibrium constant Kc for the reaction:?

  • 2SO2 + O2 <--> 2SO3 where delta h is negative. - what are the units for this constant? - will raising the temp increase the yield of the product? - will a temp rise increase the rate of equilibrium formation? - what effect will a catalyst have on the yield?

  • Answer:

    Kc = [SO3]^2/[SO2]^2[O2] = L/mole No, it will decrease the yield of SO3 and increase the amounts of SO2 and O2. The question is incomprehensible. A catalyst will have no effect on the yield.
