Well, you can look at this one of a couple different ways:
1) Look at the given base, and the stronger it's conjugate acid is, the
lower it's Kb will be right? (remember the strong acids are: HCl, HI,
HBr, H2SO4, HClO4 and HNO3.) Although if the conjugate acid isn't a
strong acid, then you will have to know the Ka of the acid, which doesn't
help very much... so...
2) Look at the periodic table, basicity is the OPPOSITE of acidity,
right? Well, since acidity increases going from L to R, then it
would stand to reason the basicity is just the opposite of this (just
look at what the relative acidities are doing and do the opposite-like a
counter-culture thang ... and if this doesn't work then ask the Prof :)
