Homework Answers
A)
ΔHo = -3352.0 KJ/mol
ΔSo = -625.1 J/mol.K
= -0.6251 KJ/mol.K
T = 298 K
use:
ΔGo = ΔHo - T*ΔSo
ΔGo = -3352.0 - 298.0 * -0.6251
ΔGo = -3165.7202 KJ/mol
Answer: -3166 KJ/mol
B)
Now we have:
ΔHo = -3352.0 KJ/mol
ΔSo = -625.1 J/mol.K
= -0.6251 KJ/mol.K
T = 5400 K
use:
ΔG = ΔHo - T*ΔSo
ΔG = -3352.0 - 5400.0 * -0.6251
ΔG = 23.54 KJ/mol
Answer: 23.54 KJ/mol
