Given Δ\DeltarS0 = –266 and the listed [S0m values]

calculate S0 for Fe3O4 (s) :

4Fe3O4 (s) [..............] + O2 (g) [205] \longrightarrow 6Fe2O3 (s) [87]

A

+111.1

B

+122.4

C

145.75

D

248.25

Answer

145.75

Explanation

Solution

Δ\DeltaSreaction = 6(87) – 4X – 205 \Rightarrowx = 145.75 J/mole K
