1. Rising costs to raw materials may impel us to rise prices farther.

2. Rising costs of raw materials may impale us to raise prices further.

I'd like to know if rising costs to materials is correct. Also, what is the difference between to rise and to raise? Understand that from the Sc book, both sentences are incorrect.

Would this sentence be correct then?

Your views and comments, please. thanks.
