Given that : Δ G f O ​ ( CuO ) = − 30.4 kcal / mole Δ G f O ​ ( Cu 2 ​ O ) = − 34.98 kcal / mole T = 298 K Now on the basis of above data which of the following predictions will be most appropriate under the standard conditions and reversible reaction.

(B) Cu 2 ​ O ( s ) + 2 1 ​ O 2 ​ ( g ) ⇌ 2 CuO ( s ) Δ G ∘ reaction ​ = [ 2 × ( − 30.4 )] − [ − 34.98 ] = − 25.82 kcal and − 25.82 × 1 0 3 = 2.303 × 2 × 298 lo g K ∴ K 1 0 19 , a very high value, hence reaction will be almost completely with a trace of Cu 2 ​ O .
