"as to"

I see this pretty often, and while i still understand the sentence i'd like to know what it means exactly so that i can use it myself.
The preposition is "as to".
Here's the example: "In summary, a decrease in pressure favours the reaction that causes the number of molecules to increase, whereas an increase in pressure causes the equilibrium to shift in such a way as to reduce the number of molecules."

Now i've looked it up at dictionary.com and it gives me two definitions:
1 - With regard to
2 - According to

But when i replace these definitions in the example above it doesn't make sence.

Can someone help me out with this please?

Thanks in advance, chocolaty.
