How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lit

kolezko [41]

Explanation:

Lithium is an electropositive element that readily loses electrons.

Oxygen is electronegative and it will readily accept electrons.

Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.

2atoms of Li lose two electrons:

Li → Li²⁺ + e⁻

Lithium isoelectronic with helium

For oxygen;

O + 2e⁻ → O²⁻

Oxygen is isoelectronic with Neon

Two ions of the lithium combines with the oxygen to form the bond;

4Li + O₂ → 2Li₂O

The electrostatic attraction between the two ions forms the ionic bond

For the reaction CO2(g) + H2(g)CO(g) + H20(g)

Studentka2010 [4]

Answer:

The ΔG° is 29 kJ and the reaction is favored towards reactant.

Explanation:

Based on the given information, the ΔH°rxn or enthalpy change is 41.2 kJ, the ΔS°rxn or change in entropy is 42.1 J/K or 42.1 * 10⁻³ kJ/K. The temperature given is 289 K. Now the Gibbs Free energy change can be calculated by using the formula,

ΔG° = ΔH°rxn - TΔS°rxn

= 41.2 kJ - 289 K × 42.1 × 10⁻³ kJ/K

= 41.2 kJ - 12.2 kJ

= 29 kJ

As ΔG° of the reaction is positive, therefore, the reaction is favored towards reactant.
