Acrobat Reader for commercial use?

Hello. I recently finished an illustrated storybook, made it in LibreOffice and exported it as a PDF. Then I opened it with Adobe Acrobat Reader, but I was wondering if it´s legal to do this, because I don´t know if Adobe Acrobat Reader can be used for commercial purposes, because I´m going to send this PDF of my book to a publisher for publication, which it would be a commercial purpose. I would appreciate if someone could clarify this for me. Thank you!
