Consider a sample that is a mixture composed of biphenyl, benzoic acid, and benzyl alcohol. Predict the order of elution of the
Tems11 [23]

Answer:

biphenyl, benzyl alcohol, benzoic acid

Explanation:

Due to the nonpolar nature of cyclohexane, biphenyl will be the first solute to be eluted due to the presence of two phenyl rings. The second solute to be eluted will be benzyl alcohol due to the presence of OH group. This is because it has the ability to exhibit hydrogen bond with the silica column of the chromatography. Lastly, the benzoic acid will be the third solute to be eluted due to the presence of COOH group which is more polar than the OH group. Therefore, the order of elution of the components in the mixture is biphenyl, benzyl alcohol, benzoic acid.

Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those
Elden [556K]

Answer:

The Equilibrium will shift towards the left.

Explanation:

The reaction for the formation of nitric oxide is follows,

N_2(g)+O_2(g)\leftrightarrow2NO(g)

Expression for reaction quotient is as follows,

Q=\frac{[NO]^2}{[N_2][O_2]}

Putting the values according to the data given and calculating reaction quotient for the reaction

Q=0.16

So, the reaction quotient is 0.16.

and the value of K is 0.01 .

Q>K

Since the value of K is less than Q, therefore the reaction will shift towards left.
