They will be approved, as long as they are supported with documentation.
There may be a cut off point for when you can make an EC application. So if you didn't submit assigments already, they may now be classed as Fail/non-submissions and will be capped at resit. At my uni, retrospective EC applications are occasionally considered so, if approved, these could be commuted to fail/non-submissions with uncapped resit.
If you have already submitted work and had it graded and it has passed, those marks may have to stand (though you may be able to appeal).
It all depends on the detail and so when you do your EC application make sure to get some advice from the SU and your Personal Tutor.
