The molar solubility of lead iodide is 1.45 times 10^ - 3 M at 20 degree C and 6.85 times 10^ - 3 M at 80 degree C. What are the values of Delta H degree and Delta S degree for dissolution of PbI2? PbI( s) rightarrow Pb^(2 +) ( aq) + 2 I^( -) (aq) You may assume that Delta H and Delta S are independent of temperature
