Explanation / Answer

MO2 = M + O2 dG = 291.5

C(s) + O2(g) = CO2(g) dG = 394.36

combination:

MO2+C(s) + O2(g) = CO2(g) + M + O2 dG =291.5 394.36

cancel common terms

MO2(s)+C(s) = CO2(g) + M(s) dG = -102.86 kJ/mol

now,

dG = -RT*ln(K)

-102.86 *10^3 = (8.314*298*ln(K)

ln(K) = (102.86 *10^3)/(8.314*298)

K = exp(41.51) = 1.06*10^18
