Journal acceptance rates can be difficult to find. Some journals post their acceptance rates on thier websites, so a quick Google search of the journal title is a good starting place.
The library subscribes to a database called Cabell's that includes acceptance rates for certain journals in certain disciplines. See link on the left.
Occasionally, societies or other parties will publish acceptance rates for journals within a particular discipline. Again, a Google search may help find these. Try keywords like “acceptance rates and biology.”
You can also try to contact the editor of the journal to see if s/he will share the acceptance rate.
When you search for a journal in Bunch Library's OneSearch system, you can view the journal information in SHERPA/RoMEO and SCImago journal ranking.
SHERPA/RoMEO is a database of publishers' policies on copyright and self-archiving.
SCImago provides journal metrics based on citations from the Scopus database.
After selecting a title in OneSearch, look for the links, circled in the image below:
Identify Journals by Browsing Sources by Subject as shown below. Use the drop-down menu to browse.
Then, filter results on the left if you want to select open access journals or journals by quality ranking. 
Another way to identify journals in Scopus is to search for your research topic and then analyze the results to see what sources are publishing on your topic. Search the database as you would for a literature search.
After running the search, click the Analyze Search Results link at the top of the search results.
And finally, click on the Documents per year by source link to view the list of sources.
