Ksp values vary with temperature, so you have to specific on the temperature of the system. Also, you can search for Ksp values of each in google or from your textbook.
For the formulas, write first the balanced reaction. For example, for the first one, PbI2:
PbI2 <---> Pb(+) + 2 I(-)
Thus, its Ksp formula would be:
Ksp = [ Pb+ ] [ I- ] ^ 2
For CdS:
CdS <---> Cd(2+) + S(2-)
Thus,
Ksp = [ Cd(2+) ] [ S(2-) ]
Now try doing the others.
