5. Calcule las concentraciones cuando se alcanza el equilibrio si partimos de unas concentraciones iniciales [A]=[B]=1M ; [C]=[D

g100num [7]

Las concentraciones en el equilibrio para la reacción química presentada son:

$[A] = [B] = 1-x = 1-0.69 = 0.31 M\\[C] = [D] = x = 0.69 M$

Consideremos la siguiente reacción química genérica:

A + B ⇄ C + D

Para calcular las concentraciones en el equilibrio, debemos construir una Tabla ICE. Cada fila representa una instancia (Inicial, Cambio, Equilibrio) y la completamos con la concentración o cambio de concentración ("x" para concentraciones desconocidas). Como inicialmente no hay productos, la reacción se desplazará hacia la derecha para alcanzar el equilibrio.

A + B ⇄ C + D

I 1 1 0 0

C -x -x +x +x

E 1-x 1-x x x

La constante de equilibrio, Kc, es:

$Kc = 5 = \frac{[C][D]}{[A][B]} = \frac{x^{2} }{(1-x)^{2} } \\\sqrt{5} = x/1-x\\x = 0.69$

Las concentraciones en el equilibrio son:

$[A] = [B] = 1-x = 1-0.69 = 0.31 M\\[C] = [D] = x = 0.69 M$

Each $\sf\purple{ovary}$ is a female sex organ about the size and shape of an almond.

Explanation:-

Ovaries are the the primary female reproductive organs.
There are two ovaries which are located on either side of the uterus.
The two functions of ovaries are -i) to produce eggs (ova) and ii) to produce female hormones.
