Question

Sapling Learning When the oxide of generic metal Mis heated at 25.0 C, only a negligible amount of M is produced. Mo,(s AG 287.6 kJ mol M When this reaction is coupled to the conversion of graphite to carbon dioxide, it becomes spontaneous. What is the chemical equation of this coupled process? Show that the reaction is in equilibrium, include physical states, and represent graphite as C(s) Mo, CVs MIs) Co What is the thermodynamic equilbrium constant for the coupled reaction?

Explanation / Answer

dGo = -RTlnK

lnK = - dGo/ RT

log K = - dGo/ (2.303*RT)

log K = - 287600 J/mol / ( 2.303*8.314J/mol.K*298K)

log K = - 50.40

K = 10-50.40 => 3.94 * 10-51
