Show that the reaction `CO(g)+ 1/2 O_(2)(g) to CO_(2)(g)` at 300 K is spontaneous and exothermic, when the standard entropy change is `-0.094 kJ mol^(-1) K^(-1)`. The standard Gibbs energies of formation for `CO_2 and CO` are `-394.4 and -137.2 kJ mol^(-1)`, respectively.

Explanation

`Delta_(r)G^(@) = - 257.2 kJ lt 0, DeltaH^(@) = -285.4 kJ lt 0`
