Consider the two gaseous equilibria
SO2(g) + (1/2)O2(g) SO3(g) K1
2SO3(g) SO2(g) + O2(g) K2
The values of the equilibrium constants K1 and K2 are related by

a) K2 = K1^2
b) K2^2 = K1
c) K2 = 1/K1^2
d) K2 = 1/K1
e) none of these.

These are probably a little hard to read, but I think its none, because the SO2 is the same in both reactions where the others are different, if it was 2SO2 then it whould be 1/k^2 because the reaction is flipped...am I right? I just hope the professor didnt do a typo and forget the 2..
