0 1 This question is about silver iodide.
0 1 . 1 Define the term enthalpy of lattice formation.
[2 marks]
0 1 . 2 Some enthalpy change data are shown in Table 1.
Table 1
Enthalpy change
/ kJ mol−1
AgI(s) Ag+(aq) + I– +112
(aq)
Ag+(g) Ag+(aq) 464
I–(g) I–(aq) 293
Use the data in Table 1 to calculate the enthalpy of lattice
formation of silver iodide.

0 1 . 3 A calculation of the enthalpy of lattice formation of silver iodide based
on a
perfect ionic model gives a smaller numerical value than the value
calculated in Question 1.2
Explain this difference.
