B/W film mistakenly developed in C41

What result would be expected if a roll of asa 400 fujifilm b/w were
developed by mistake in c41 chemistry?

I take it that this is *not* chromogenic (C41) B&W film? Just checking.

I hope that in a few years it [Wikipedia] will be so bloated that it
will simply disintegrate, because I can't stand the thought that this
thing might someday actually be used as a serious reference source.
Because in its current form, it's not to be taken seriously at all.

You'll end up with blank film. All chromogenic films use bleach to
turn all the silver into soluble silver salts and which are removed in
the fix. Sometimes they are combined in a bleach-fix, "blix." If you
run an ordinary black and white film through a color process you'll have
a bunch of silver to recover from your fix and not much else. Sorry.

I found my answer elsewhere. Thanks anyway.

The bleach step will completely wipe the film. Do not get c-41 bleach near
b&w film!
My limited experiments show that the c-41 developer is fairly "weak" for B&W
film. It must be used at 100F and the time for Tri-X is in the 7-10 minute
range, instead of the 3:15 for color film. Contrast is a bit low; #3 or 4
filter instread of #2.
The c-41 fixer is also a bit weak. For color film the fix time is 6:30 at
100F. For complete clearing of B&W film, it's more like ten minutes.

If you absolutely had to develope B&W film in c-41 chems, it will work.

You will get a piece of blank film.

You would have almost clear film.
