Why caps in paralell?

[walid]

the caps at the right, why 10p//15p? what if use one 25p cap?
thanks

25pf is not a standard value. 10pF, 15pf, 22pF and 27pF are standard values.

Not that it matters, 22pf or 27pf could be used instead.

Another reason for using many capacitors in parallel is it gives lower impedance to higher frequencies if they're spread across the PCB traces.

I understand from your words that if I had two caps, one of them is equal to 5p and the second = 10p.
 Better to use the two in parallel to get 15p and not one 15p to make an easy path for the high-frequencies toward ground???
