Which of the following statements are incorrect?

Question

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

Answer 1

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.
