1.	Show that the reaction CO+1//2O_2 to CO_2 at 300 K is spontaneous. The standard Gibbs free energies of formation of CO_2 and COare -394.4 and -137.2 "kJ mole"^(-1)respectively.
Answer» Solution :`CO+1//2O_2 to CO_2` `DeltaG_"(REACTION)"^0=sum G_(f"(products)")^0-sum G_(f"(reactants)")^0` `DeltaG_"(reaction)"^0=[G_(CO_2)^0]-[G_(CO)^0+1/2G_(O_2)^0]` `DeltaG_"(reaction)"^0`=-394.4+[137.2+0] `DeltaG_"(reaction)"^0=-257.2 "kJ MOL"^(-1)` `DeltaG_"(reaction)"` of a reaction at a given temperature is NEGATIVE hence the reaction is spontaneous
