Interpretation Introduction

(a)

Interpretation:

The absorbance that minimizes the concentration uncertainty is to be stated.

Concept introduction:

The molecular absorption spectroscopy is the device that measures the transmittance and absorbance of the solution in the transparent container. The transparent container or cell having path length b.

Beer’s law shows the linear relation between the absorbance and concentration of the observing analyte.

A=logT=logP0P=εbc

Here, A is the absorbance, T is the transmittance, ε is the molar absorptivity, c is the concentration, P0 is the incident power and P is the transmitted power after passing through the sample.

Interpretation Introduction

(b)

Interpretation:

The expression for transmittance and absorbance that minimizes the concentration uncertainty is to be stated.

Concept introduction:

The molecular absorption spectroscopy is the device that measures the transmittance and absorbance of the solution in the transparent container. The transparent container or cell having path length b.

Beer’s law shows the linear relation between the absorbance and concentration of the observing analyte.

A=logT=logP0P=εbc

Here, A is the absorbance, T is the transmittance, ε is the molar absorptivity, c is the concentration, P0 is the incident power and P is the transmitted power after passing through the sample.

Interpretation Introduction

(c)

Interpretation:

Whether the spectrophotometer was operating under Case I, Case II or Case III conditions is to be stated.

Q2. Consider the hydrogenation of ethylene C2H4 + H2 = C2H6 The heats of combustion and molar entropies for the three gases at 298 K are given by: C2H4 C2H6 H2 AH comb/kJ mol‍¹ -1395 -1550 -243 Sº / J K¹ mol-1 220.7 230.4 131.1 The average heat capacity change, ACP, for the reaction over the temperature range 298-1000 K is 10.9 J K¹ mol¹. Using these data, determine: (a) the standard enthalpy change at 800 K (b) the standard entropy change at 800 K (c) the equilibrium constant at 800 K.
