Interpretation Introduction

(a)

Interpretation:

The method of correcting the following error in the TLC chromatography procedure needs to be explained.

There is only one spot obtained from a mixture of two components namely 1-octene and 1,4-dimethylbenzene with retention factor 0.95 in the presence of acetone as a solvent.

Concept Introduction:

The method of separation of components of the mixture is done by column chromatography techniques. This method is used to isolate the large number of components. The movement of solvent molecules in the thin layer chromatography takes place from bottom to top but in the column chromatography, the movement of mobile phase takes place from top to bottom in the column.

Interpretation Introduction

(b)

Interpretation:

The method of correcting the following error in the TLC chromatography procedure needs to be explained.

There is only one spot obtained from a mixture of two components namely dicarboxylic acid and tricarboxylic acid with retention factor 0.05 in the presence of hexane as a solvent.

Concept Introduction:

The method of separation of components of the mixture is done by column chromatography techniques. This method is used to isolate the large number of components. The movement of solvent molecules in the thin layer chromatography takes place from bottom to top but in the column chromatography, the movement of mobile phase takes place from top to bottom in the column.

Interpretation Introduction

(c)

Interpretation:

The method of correcting the following error in the TLC chromatography procedure needs to be explained.

In the developed TLC plate, the solvent front ran off the top of the plate.

someone else has already submitted the same question on here and it was the incorrect answer.
The reaction: 2NO2(g) ⇌ N2O4(g) is an exothermic reaction, ΔH=-58.0 kJ/molrxn at 0°C the KP is 58.If the initial partial pressures of both NO2(g) and N2O4(g) are 2.00 atm:A) Is the reaction at equilibrium? If not, what is the value of Q? B) Which direction will the reaction go to reach equilibrium? C) Use an ICE table to find the equilibrium pressures.
