&lt;br /&gt;
===Exam 26th August 2022===&lt;br /&gt;
The exam is open book. You can take the book by prof. Ceulemans and the printed pages of the exercise sessions.&lt;br /&gt;
&lt;br /&gt;
====Question 1 (4/20)====&lt;br /&gt;

*i*i=j*j=k*k=-e&lt;br /&gt;
*i*j*k=-e&lt;br /&gt;

# Is the group cyclic. Explain your reasoning.&lt;br /&gt;
&lt;br /&gt;
====Question 2 (10/20)====&lt;br /&gt;
Given is the molecule C4H2N2 (trans)&lt;br /&gt;
# What is the point group of this molecule?&lt;br /&gt;
# Do a full coordinate analyis. Give the irreps of the rotational, translational and vibrational displacements.&lt;br /&gt;
# What irreps will be visible in the IR spectrum?&lt;br /&gt;
# There are 10 pi-electrons. Give the irreps of the orbitals involved. (Unsure about this question, but it did involve the pi-system)&lt;br /&gt;
# The ground state evolves according to the totally symmetric irrep. What excitations would vibrationally couple with the ground state?&lt;br /&gt;
&lt;br /&gt;
====Question 3 (6/20)====&lt;br /&gt;
ML6 with Oh point group and 8 d-electrons. (Similar to Q4 exercise session 5)&lt;br /&gt;
# Identify d-electron configuration of lowest energy state.&lt;br /&gt;
# Give the term symbols of the ground state. Start from the character table and work out the necessary direct products. No need to take spin into account.&lt;br /&gt;
# If we excite 1 electron give the term symbols. Take into account spin.&lt;br /&gt;
# What excitations would be optically visible.&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;[[Categorie:Machemie]]&lt;br /&gt;
&lt;br /&gt;
==Vakinformatie==&lt;br /&gt;
Vak van 6 stp gedoceerd door Koen Clays en Jérôme Loreau. Bestaat uit 2 delen: Advanced Chemical Kinetics en Dynamics of Chemical and Biochemical Systems, het laatste deel wordt gedoceerd door Clays en was voordien een vak op zichzelf (kijk naar die examenwikipagina voor oudere vragen).&lt;br /&gt;
Dynamics of Chemical and Biochemical Systems is een mondeling examen, bevattende hoofdstukken over (1) stabiliteit, (2) fluctuaties, (3) diffusie, (4) Langevin, (5) relaxatie, (6) evolutie. Het laatste hoofdstuk werd de laatste 2 jaar weggelaten.&lt;br /&gt;
&lt;br /&gt;
==Examenvragen==&lt;br /&gt;
===29th August 2022===&lt;br /&gt;
====Advanced Chemical Kinetics====&lt;br /&gt;
# Given the ozone reaction that happens in the earths stratosphere. What method would be the most accurate to describe the rate constant? (justify)&lt;br /&gt;
# Question about TST&lt;br /&gt;
 1) Write down the expression for the rate constant in TST. Explain the different elements.&lt;br /&gt;
 2) Given are Qtrans and Qrot equations (Qel and Qvib can be neglected). Describe the temperature dependency of the rate constant for the following reactions (both have non-linear TS):&lt;br /&gt;
*F + H2 --&amp;gt; HF + H&lt;br /&gt;
*non-linear molecule + linear molecule --&amp;gt; non-linear molecule (Was specific, but don&#039;t remember the molecules)&lt;br /&gt;
3. Exercise 2.3&lt;br /&gt;
&lt;br /&gt;
====Dynamics of Chemical and Biochemical Systems====&lt;br /&gt;
# Explain how we get from the entropy maximum of the second law of thermodynamics to the minimum in energy. Explain what role fluctuations play here and explain the probability.&lt;br /&gt;
# Explain the relation between Fick&#039;s laws, Langevin equation and the einstein equation. (He said no derivation was necessary) Explain correlation between the diffusion constant and temperature and friction.&lt;br /&gt;

 1) Leid voor beide reacties de reactie rate af (tweede met steady state approximation)&lt;br /&gt;
 2) Wat is de orde van elke reactie en de bijboherende units (2de orde; unit = cm^-3/s)&lt;br /&gt;
 3) Teken het energieprofiel ifv reactie coordinaat&lt;br /&gt;
 4) Welke quantum dynamische techniek verkies je: time independent of time dependent? (Time dependent wegens reacties met meer dan 4 atomen. Dit is niet doenbaar voor time independent)&lt;br /&gt;
 5) Welke technieken zou je nog kunnen gebruiken voor de k te berekenen? (hard sphere, tst, capture theory, classical)&lt;br /&gt;
 6) Stel de reactie, die exotherm is, heeft een late barrière. Welke energie is nodig voor deze te overbruggen? (Polanyi&#039;s rules, E(vibratie) nodig) &lt;br /&gt;
2. Oefening 3 van Chapter 2 met als extra vraag de delen van de k(hard sphere) uit te leggen.&lt;br /&gt;

Vak van 6 stp gedoceerd door Koen Clays en Jérôme Loreau. Bestaat uit 2 delen: Advanced Chemical Kinetics en Dynamics of Chemical and Biochemical Systems, het laatste deel wordt gedoceerd door Clays en was voordien een vak op zichzelf (kijk naar die examenwikipagina voor oudere vragen).&lt;br /&gt;
Dynamics of Chemical and Biochemical Systems is een mondeling examen, bevattende hoofdstukken over (1) stabiliteit, (2) fluctuaties, (3) diffusie, (4) Langevin, (5) relaxatie, (6) evolutie. Het laatste hoofdstuk werd de laatste 2 jaar weggelaten.&lt;br /&gt;

d. There are 10 pi-electrons. Give the irreps of the orbitals involved. (Unsure about this question, but it did involve the pi-system)&lt;br /&gt;
e. The ground state evolves according to the totally symmetric irrep. What excitations would vibrationally couple with the ground state?&lt;br /&gt;
&lt;br /&gt;
==Question 3 (6/20)==&lt;br /&gt;
3. ML6 with Oh point group and 8 d-electrons. (Similar to Q4 exercise session 5)&lt;br /&gt;
a. Identify d-electron configuration of lowest energy state.&lt;br /&gt;
b. Give the term symbols of the ground state. Start from the character table and work out the necessary direct products. No need to take spin into account.&lt;br /&gt;
c. If we excite 1 electron give the term symbols. Take into account spin.&lt;br /&gt;
d. What excitations would be optically visible.&lt;/div&gt;</summary>
