Hi,

For reversible reaction, does thermodynamic equilibrium constant (K) depend on the catalyst used in the reactor?
If not, it will be the same for certain reaction no matter what catalyst is, right?

One more thing.
Does n-butene include cis-2-butene and trans-2-butene?

Thanks

As far as I remember, catalyst does not affect the equilibrium constant. It affect the reaction kinetics, i.e. the time needed till equilibrium conditions are established.

Zauberberg is correct. Equilibrium is totally independent of cny catalyst used. The catalyst merely changes the rate at which equilibrium is approached, but not the equilibirum itself (whether reversible or not:rolleyes: ). I'm pretty sure that your second question can be answered, "Yes". n-butene comes in two "flavors", cis and trans. The "2" part seems redundant to me since butene-1 would not have cis and trans flavors, Still, it could well be the "proper" way of labelling these compounds.
