The equilibrium constant, K, for the following reaction is 5.10X10 at 548 K. NH_CH(s) 2 NH3(E) + HC1(2) Calculate the equilibriu

Serga [27]

Answer:

The equilibrium concentration of HCl is 0.01707 M.

Explanation:

Equilibrium constant of the reaction = $K_c=5.10\times 10^{-6}$

Moles of ammonium chloride = 0.573 mol

Concentration of ammonium chloride = $\frac{0.573 mol}{1.00 L}=0.573 M$

$NH_4HCl(s)\rightleftharpoons 2 NH_3(g) + HCl(g)$

Initial: 0.573 0 0

At eq'm: (0.573-x) x x

We are given:

$[NH_4Cl]_{eq}=(0.573-x)$

$[HCl]_{eq}=x$

$[NH_3]_{eq}=x$

Calculating for 'x'. we get:

The expression of $K_{c}$ for above reaction follows:

$K_c=\frac{[HCl][NH_3]}{[NH_4Cl]}$

Putting values in above equation, we get:

$5.10\times 10^{-6}=\frac{x\times x}{(0.573-x)}$

$2.9223\times 10^{-6}-5.10x\times 10^{-6}=x^2$

$x^2-2.9223\times 10^{-6}+(5.10\times 10^{-6})x=0$

On solving this quadratic equation we get:

x = 0.01707 M

The equilibrium concentration of HCl is 0.01707 M.

The difference between simple diffusion and facilitated diffusion is that facilitated diffusion

Sholpan [36]

Answer:

Simple and facilitated diffusion are both similar types of phenomenon where the substances are moved from a region of high concentration to lower concentration across a semi-permeable membrane.

The main difference between them is that the facilitated diffusion requires a special type of protein or carrier molecules in order to transport the substances whereas simple diffusion does not require such molecules. The rate of flow of these substances is high in the facilitated diffusion in comparison to the simple diffusion.
