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 CO are -394.4 and -137.2 `"kJ mole"^(-1)` respectively.

Text Solution

Verified by Experts

`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
