Question

sapling learning When the oxide of generic metal M s heated at 25.0 C, only a negligible amount of M s produced. Mo, (S) FA M(s ole) AGO 290.5 kJ/ mol 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) click to edit Mo, C s What is the thermodynamic equilbrium constant for the coupled reaction? Number

Explanation / Answer

The reaction,

MO2(s) + C(s) <====> M(s) + CO2(g)

Equilibrium constant calculation,

delat Go = -RT lnK

290500 = -8.314 x 298 lnK

K = 1.20 x 10^-51
