Water

Liquids: Sound travels faster in liquids than in gases because molecules are more tightly packed. In fresh water, sound waves travel at 1,482 meters per second (about 3,315 mph). That's well over 4 times faster than in air!

Answer: The value of $K_p$ is 324

Explanation:

We are given:

Initial pressure of $S_8(g)$ = 1.00 atm

The chemical equation for the conversion of $S_8(g)$ to $S_2(g)$ follows:

$S_8(g)\rightleftharpoons 4S_2(g)$

Initial: 1

At eqllm: 1-x 4x

We are given:

Equilibrium partial pressure of $S_8(g)=0.25atm$

Evaluating the value of 'x', we get:

$\Rightarrow (1-x)=0.25\\\\\Rightarrow x=1-0.25=0.75$

The expression of $K_p$ for the above reaction follows:

$K_p=\frac{(p_{S_2})^4}{p_{S_8}}$

$p_{S_2}=4x=(4\times 0.75)=3atm$

$p_{S_8}=0.25atm$

Putting values in above expression, we get:

$K_p=\frac{3^4}{0.25}\\\\K_p=324$

Hence, the value of $K_p$ is 324

What is a supersaturated solution?

sergey [27]

Supersaturation is a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.
