An ionic bond is formed when there are more or less electrons that normal in bonding atoms.

<h3>What are Ionic bonds?</h3>

An ionic bond is formed when one atoms donates electrons to another specie to form an ion pair. One atom is positively charged while the other specie is negatively charged.

Hence, an ionic bond is formed when there are more or less electrons that normal in bonding atoms.

Considere la siguiente reacción: H, (g) +1, (a) = 2 HI (9). K, para la reacción es 54.3 a 430°C. Si se coloca H, 0.00623M, 0.004
bearhunter [10]

Answer:

[HI] = 0.0255M

[H₂] = 0.00466M

[I₂] = 0.00257M

Explanation:

Para la reacción:

H₂(g) + I₂(g) ⇄ 2HI(g)

La constante de equilibrio, K, se define como:

54.3 = [HI]² / [H₂] [I₂]

Donde cada concentración [] será la concentración en equilibrio para cada especie

Para saber la dirección del equilibrio definiremos Q como:

Q = [HI]² / [H₂] [I₂]

Donde las concentraciones [] serán las concentraciones actuales de cada gas

Reemplazando:

Q = [0.0224M]² / [0.00623M] [0.00414M]

Q = 19.5

Como Q<K, la reacción se desplazará hacia la derecha produciendo más [HI]. Así, las concentraciones en equilibrio serán:

[HI] = 0.0224M +2X

[H₂] = 0.00623M - X

[I₂] = 0.00414 - X

54.3 = [0.0224M +2X]² / [0.00623M - X] [0.00414M - X]

54.3 = 0.00050176 + 0.0896 X + 4 X² / 0.0000257922 - 0.01037 X + X²

0.00140052 - 0.563091 X + 54.3 X² =  0.00050176 + 0.0896 X + 4 X²

0.00089876 - 0.652691 X + 50.3 X² = 0

Resolviendo la ecuación cuadrática:

X = 0.001566M → Solución verdadera

X = 0.01141M → Falsa solución. Produciría concentraciones negativas

Reemplazando:

[HI] = 0.0224M +2*0.001566M

[H₂] = 0.00623M - 0.001566M

[I₂] = 0.00414 - 0.001566M

[HI] = 0.0255M

[H₂] = 0.00466M

[I₂] = 0.00257M

Siendo estas últimas, las concentraciones de las especies luego de alcanzar el equilibrio.
