Answer:

The correct answer are option B and D.

Explanation:

ΔG° = ΔH° - TΔS°

Where:

ΔG° = Gibbs's free energy of the reaction at temperature T.

ΔH° = Enthalpy of the reaction at temperature T.

ΔS° = Change in entropy of the reaction at temperature T.

  • If the vales of Gibb's free energy is less than zero or negative than the reaction is said to be spontaneous that is feasible under given conditions.
  • If the vales of Gibb's free energy is greater than zero or positive than the reaction is said to be non spontaneous that is non feasible under given conditions.

From the given reaction, the reaction with value of \Delta G_{f}^o  represents the a feasible way to synthesize the product. So, the correct answer are option B and D.

Why does hydrogen have a -1 oxidation state in the compound NaH?
ruslelena [56]

your answer will be :

B. <u>Na has a lower</u> <u>electronegativity than H</u>

because Na belongs to alkali metals which are least electronegative (most electro positive) but hydrogen is a non metal, it has higher electronegativity as compared to metals like Sodium (Na).
