Question

Select correct statement (A) In the decomposition of an oxide into oxygen and solid/liquid metal, entropy increases. (B) Decomposition of an oxide is an endothermic change. (C) To make Δ Go negative, temperature should be high enough so that T Δ So > Δ Ho. (D) All statements are correct

Tardigrade Admin · Accepted Answer

(a) When the oxide undergoes a phase change, there will be an increase in the entropy of the oxide.
(b) It is true statements,

H g O Δ H g + I /2 O_{2}

(c) For a reduction process the change in the free energy,

Δ G^{o}

must be negative and to make

Δ G^{o}

negative temperature should be high enough so that

T Δ S^{o} > Δ H^{o}

Q. Select correct statement

In the decomposition of an oxide into oxygen and solid/liquid metal, entropy increases.

Decomposition of an oxide is an endothermic change.

To make $Δ G^{o}$ negative, temperature should be high enough so that $T Δ S^{o} > Δ H^{o}$ .

All statements are correct
