1. Chemical thermodynamics and chemical kinetics study two
different aspects of
chemical reactions. Explain what these are and how they are
related.
2. Describe some of the advantages of studying the mechanisms of
chemical reactions.
3. Derive an expression for t½ for a second order reaction (Rate =
k[A]2).
For each of the following five reactions,
circle the specific chemical species that is:
reduced, and draw a box around the
specific chemical species that is oxidized:
a) MnO2 (s) + 2 I- (aq) +4 H+
(aq) --> Mn2+ (aq) + I2 (aq) + 2
H2O (l)
b) Cd (s) + 2 NiO(OH) (s) + 2 H2O (l) --> 2
Ni(OH)2 (s) + Cd(OH)2 (s)
c) NH4+ (aq) + 2 O2 (g) -->
NO3- (aq) + 2 H+ (aq) +...
1. Give examples of three important types of chemical reactions
that occur in biochemical systems.
2. How is a standard thermodynamic state defined for biochemical
systems?
3. Explain what is meant by a term "substrate cycle."
4. What is the critical limitation for formation of
carbon-carbon bonds in biochemical systems?
5. Explain why most fatty acids within the body have an even
number of carbon atoms.
6. List three vital functions served by amino acids in the
body.
1. What are the 10 common elementary steps in chemical reactions and why is important to know these elementary steps in organic chemistry?
2.For each elementary step, give an example of that step that happens in a chemical reaction? (Please show all work)
Give a general description of the light and dark reactions of
photosynthesis. Light – light energy is converted into chemical
energy (ATP) Dark – Carbon fixation – carbon is fixed into organic
molecules (sugars) using ATP and enzymes

a. Exergonic
b. Dangerous
c. Endergonic
d. Activation
e. Photosynthesis
2- In lab, catalase will be used to initiate a particular
chemical reaction that breaks hydrogen peroxide down into water and
oxygen gas. Which is the substrate in this reaction?
Select one:
a. Hydrogen
b. Catalase
c. Hydrogen peroxide
d. Water
e. Oxygen gas...
