When K is 0, <1, and >1, what is ∆G's sign??

K = 0 then delta G = 0
K < 1 then delta G > 0
K > 1 then delta G < 0

When delta G is zero the equation is at equilibrium so K=1.

This can be seen using ΔG = -RTlnK

When K>1, then lnK is positive, and ΔG is negative.
When K<1, then lnK is negative, and ΔG is positive.

Using the equation ΔG = -RTlnK.
ln 1=0 thus when K=1, ΔG = 0

K = 0 ; delta G = 0
K < 1 ; delta G > 0
K > 1 ; delta G < 0
