Which of the following statements are incorrect?
1) Gases are not included in the equilibrium constant expression.
2) Equilibrium constant can be increased by adding a catalyst
3) Large equilibrium constant favors reactants
4) Equilibrium is typically achieved in a very short time
5) Equilibrium can only be achieved if reactants are mixed in stoichiometric proportions

I think that it's only statement 4.. i was thinking about 3 too but I left it to stay on the safeside. I'd love to get someone elses point of view on this problem

    1) Gases are not included in the equilibrium constant expression.They are included so this is incorrect.
    2) Equilibrium constant can be increased by adding a catalyst.They can not be changed by adding a catalyst so this is incorrect
    3) Large equilibrium constant favors reactantsLarge Keq favors products so this is incorrect.
    4) Equilibrium is typically achieved in a very short time Equilibrium time varies; therefore, this is incorrect.
    5) Equilibrium can only be achieved if reactants are mixed in stoichiometric proportions This is incorrect.
