The numerical value of the concentration
equilibrium constant for the gaseous reaction
2 SO2 + O2
*)
2 SO3
is 0.5 at temperature T. When a reactionmix-
ture is brought to equilibrium, [O2] is found
to be 2.0 M and [SO3] is found to be 10 M.
What is the equilibrium concentration of SO2
in this reaction mixture?

  • apchemistry -

    ............2SO2 + O2 ==> 2SO3
    E...........x.....2.0M....10M
    Substitute the values into the Kc expression and solve for the one unknown.
