The part that is broke open when you smack the pack does not actually contain the yeast. You can brew with those unsmacked. From my understanding, the smack pack is just to ensure the viability of the yeast.
Did the pack swell up?

1. Is the yeast in the small inner packet or in the foil pouch itself?
The yeast is in the main foil pouch. The small inner packet contains the sterile nutrient and wort that feeds the yeast before it is added to your fermenter.
2. Can I use an Activator package without activating it and waiting for it to swell? ?
Yes. An Activator pack has enough yeast in it to pitch 5 gallons whether it is activated or not. There will only be a slightly longer lag time if the package is not activated before use. In any case, the nutrient pack should be popped before using because it contains valuable nutrients.
hope this helps..
