Question

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

Answers

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