Methods of Hawking radiation generation

[Leyzorek]

first question
From what i read Hawking radiation is a particle and ant particle created on the event horizon of a black hole, one particle is pulled into the black hole letting the other escape, why does the one outside of the event horizon escape instead of both being pulled in? It would still need an enormous amount to energy to escape the black holes gravity.
2nd question
I have read that the amount of hawking radiation emitted by a black hole increases as the black hole shrinks. why is this?

Yes, this is how you find it described in pop-science presentations but not in actual physics texts. As Hawking explained it, the particle-pair thing is NOT an actual description of what happens but rather a heuristic that is the best he could come up with to describe in English what really can only be described in the math.

For the pop-sci description, the particle pair members have momentum opposite each other.
