Is it acceptable to ask a recruiter what questions they are going to be asking?

I have a phone interview scheduled with an employer I've been trying to work at forever.

The recruiter emailed me asking for a 30 minute phone interview which kind of concerns me because I'm usually used to 10-15 minute phone interviews. So I'm assuming there's more questions than the usual.

Is it acceptable and fine for me to ask the recruiter what questions they will be asking me so I can prepare for this phone interview much better?
