[Fellowship of the Ring] Does Arwen give up her immortality to save Frodo?

When they're fleeing from the Ringwraiths and Frodo is dying, she prays over him, saying, "What grace is given me, let it pass to him." I know this scene isn't in the book, but given the wider Tolkein-verse, is it possible movie-Arwen is passing some of her immortality to him?

It is just a generic prayer.  Immortality cannot simply be "passed" to someone else.  Arwen does give up her immortality to be with Aragorn, but she is able to do this for completely separate reasons relating to her family's history.
