It depends on how much detail you want. Just about any basic book on photography will tell you about the exposure/development process.(posted 8852 days ago)If you want a lot more information there is "The Darkroom Cookbook" and "The Film Developing Cookbook." These go into the chemistry to the extent of telling what the various chemicals used actually do.
For the most detail is the book by Stoebel, something like Photographic Processes and something. I forget right now. But this is a college textbook level book on the entire photographic process.
