Select correct statementA. In the decomposition of an oxide into oxyhen and solid//liquid metal, entropy increases.B. Decomposition of an oxide is an endothermic change.C. To make `DeltaG^(@)` negative, temperature should be high enough so that `TDeltaS^(@)gtDeltaH^(@)`.D. All statements are correct. |

Answer» Correct Answer - D (a)When the oxide undergoes a phase change, there will be an increase in the entropy of the oxide. (b) It is ture statements, `HgOoverset(Delta)rarrHg+1//2O_(2)` (C) For a reduction process the change in the free energy, `DeltaG^(@)` must be negative and to make `DeltaG^(@)` negative temperature should be high enough so that `T DeltaS^(@)gtDeltaH^(@`. |
