Answer 3

catalysts are used to speed up the rate of recation. useful because the catalyst itself isn't consumed and can be reused.

Answer 4

Depends on the catalyst, really, as some are used to decrease the speed of a reaction('negative catalysts' or inhibitors), but generally we'd say it would increase it.

Answer 5

one answer i saw was that if wouldn't effect it

Answer 6

It wouldn't affect the equilibrium, yes, because the rates of both forward and reverse reactions would increase equally.
