Question
The synthesis of solid lead (II) sulfide can be expressed in the equation
Pb(s) + S(s) → PbS(s)
AH° = - 98.7 kJ/mole
Pb(s) → Pb(g)
AH° (1)
Pb(g) → Pb*2(g) + 2 e!
AH° (2)
S(s) → S(g)
AH° (3)
S(g) + 2 e1 → s'(g)
AH° (4)
Pb*(g) + s?(g) → PbS(s)
AH° (5)
19. Which of the following will have the same numerical value as the lattice energy?
(A)
ΔΗ"(1) + ΔΗ(2)
(B)
AH°(3)
(C)
AH°(4)
(D)
AH°(5)
