How competitive is Chemistry at JHU / Brown / UCLA / NYU / Georgetown?

I am considering the following colleges : JHU, Brown, UCLA, NYU and Goergetown, even though I have not fully decided yet.

I was just wondering how competitive is Chemistry at these institutions?
I am split between chem and biochem, and was just curious about the stats. which major is considered more competitive / difficult to get into?

thank you!
