Google does not release that kind of information. Many Adsense users would die to find out (including myself).
Google never say about the CPC rates because it varies depending upon the keywords of the ads. So just put the ads and if you think it is low paying then filter it.
They make an average of 8 cents per click. That's why if you have ads up that cost 10 cents to the advertiser you make about 2 cents per click, if your ads cost 20 cent you'll make more like 12 cents.
