Gibbs Free Energy/ Thermochemistry
1. Calculate the equilibrium constant at the temperature given
O2(g) +2F2(g) --> 2F2O (g) (T=100 C)
Delta G -79 KJ
Homework Answers
T= 100.0 oC
= (100.0+273) K
= 373 K
ΔGo = -79 KJ/mol
ΔGo = -79000 J/mol
use:
ΔGo = -R*T*ln Kc
-79000 = - 8.314*373.0* ln(Kc)
ln Kc = 25.4747
Kc = 1.157*10^11
Answer: 1.16*10^11
