Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 5.0L
Yanka [14]

Answer:

Kp = 7.4727

Explanation:

Let's write the balanced equilibrium reaction:

2NH₃ <-------> N₂ + 3H₂     Kp = ??

Now, if we want to calculate the Kp, we need to write an ICE chart with this reaction, which is the following:

         2NH₃ <-------> N₂ + 3H₂  

I.         4,5                 0        0

C.       -2x                +x     +3x

E.        4,5-2x            x       3x

According to this chart, the Kp expression should be:

Kp = (PH₂)³ * (PN₂) / (PNH₃)²   (1)

The value of x, we already know it because the problem states that the amount of nitrogen gas is 1.1 atm, so replacing this value into (1) we have:

Kp = (3*1.1)³ * (1.1) / (4.5 - (2 * 1.1))²

Kp = 39.5307 / 5.29

<h2>Kp = 7.4727</h2>

Hope this helps

A mixture of benzoic acid and naphthalene was dissolved in tert-butyl methyl ether and the resulting solution was extracted with
Llana [10]

Answer:

C₆H₅COOH Benzoic Acid

Explanation:

Here we are using the extraction method to separate  benzoic acid from naphtalene in the  ether solution  by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate  ( naphtalene remains in the organic layer )  .

The sodium benzoate  is completely soluble in the aqueous layer being a salt, and  reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid  since the it is insoluble in water hence  separating it.
