Why does a CO2 filled balloon deflate quicker than a helium filled balloon given that helium atoms are smaller and monatomic?

Well...it's because they're not the same balloons. There is a product out there called Super Hi-Float.

You probably wouldn't do this with a balloon you're going to fill with CO2.
