Question Will a ryzen 5 2600 work on a dell 0XFRWW motherboard?

It's physically compatible. But whether Dell has the BIOS allowing for such an upgrade is questionable.

Best check the original configurations Dell offered to see for better compatibility chances. Or see if anyone with that precise motherboard is using it with the Ryzen 5 2600 on Userbenchmark; though do so with some scepticism if it will definitely work with yours.
