Description

I need a sample draft for this multipart chemistry question.

Please see attached documents for the questions that are to be answered.

CHEM1068 Introduction to Chemistry III
Thermodynamics Tutorial #2
for Week X
Note: Completed assignments are to be uploaded by 12th April 2021 at 9:00 am in
myelearning assignment folder Use thermodynamic data from Appendix 7(p. 1348),
of Chemistry3 (burrows et al) for these calculations and read Atkins Physical Chemistry
10th Eds
1. Calculate the entropy change when 2.50 mole of sulphur dioxide gas are heated from 25 °C
to 70 °C at constant pressure. (Cp for SO2 (g) is 39.87 JK-1mol-1)
(5 marks)
2. Using data in Burrows et al, Calculate the standard entropy changes of reaction at 298 K for
the following reactions:
(a) N2(g)+3H2(g)ï‚® 2NH3(g)
(b) N2O4 (g)ï‚® 2NO2 (g)
 r S 0   S 0 ( products)   S 0 (reac tan ts)
(6 marks)
3. Using data in Burrows et al book, Calculate the standard Gibbs energy change for the
combustion of β-glucose
C6H12O6(β-glucose)(s) + 6O2(g) 6CO2 (g) + 6H2O (g)
at (a) 298 K and (b) 650 K. Compare the values calculated.
 r G 0   r H 0  T r S 0
(equation1)
(6 marks)
4. In the gas phase reaction
2𝐴 + 𝐵 ⇌ 3𝐶 + 2𝐷
It is found that when1.00 mole A, 2.00 moles B and 1.00 mole D were mixed and allowed to
come to equilibrium at 25oC, the resulting mixture 0.9 mole C at a total pressure of 1 bar.
Calculate:
(i)
Mole fraction of each species at equilibrium
(ii)
Mole fraction equilibrium Kx
(iii)
Equilibrium K
(iv)
∆𝑟 𝐺 𝜃

5. To improve air quality and obtained a useful product, chemist often remove sulphur from coal
and natural gas by treating the contaminant hydrogen sulphide with oxygen:
2𝐻2 𝑆(𝑔) + 𝑂2 (𝑔) ⇌ 2𝑆(𝑠) + 2𝐻2 𝑂(𝑔)
Given the standard Gibbs free energy of formation in table 1

Table 1
If reaction quotient (Q) = 0.1, total pressure is 1 bar
Do you expect the above reaction to be spontaneous? In answer use a free energy versus
reaction progress (label the portions that relate to ∆𝑟 𝐺 𝜃 𝑎𝑛𝑑 ∆𝑟 𝐺).
