Answer #1

Given:

Gof(SO2(g)) = -300.2 KJ/mol

Gof(O2(g)) = 0.0 KJ/mol

Gof(SO3(g)) = -371.1 KJ/mol

Balanced chemical equation is:

2 SO2(g) + O2(g) ---> 2 SO3(g)

ΔGo rxn = 2*Gof(SO3(g)) - 2*Gof( SO2(g)) - 1*Gof(O2(g))

ΔGo rxn = 2*(-371.1) - 2*(-300.2) - 1*(0.0)

ΔGo rxn = -141.8 KJ

We have:

T = 298.15 K

ΔGo = -141.8 KJ/mol

ΔGo = -141800 J/mol

use:

ΔGo = -R*T*ln Kc

-141800 = - 8.314*298.15* ln(Kc)

ln Kc = 57.2047

Kc = 6.977*10^24

Answer: 6.98*10^24
