Step by step solution

01

Step-by-Step SolutionStep 1: Full-headed and Half-headed curved arrows

A full-headed arrow is used to indicate the movement/transfer of a pair of electrons.

A half-headed arrow indicates the transfer of a single electron.

02

Movement of electrons in reaction a and b

The movement of electrons in reactions a and b are as follows:

a.

Reaction a

b.Reaction b

03

Movement of electrons in reaction c and d

The movement of electrons in reactions c and dare as follows:

c.

Reaction c

d.Reaction d

Given each value, determine whether the starting material or the product is favored at equilibrium.

a.Keq=0.5

b.∆G°=-100kJ/mol

c.∆H°=8.0kJ/mol

d. Keq=16

e.∆G°=-2.0kJ/mol

f.∆H°=200kJ/mol

g.∆S°=8J/(K.mol)

h.∆S°=-8J/(K.mol)

Label each statement as true or false. Correct any false statement to make it true.

a. Increasing temperature increases reaction rate.

b. If a reaction is fast, it has a large rate constant.

c. A fast reaction has a large negative ∆G°value.

d. When Eais large, the rate constant k is also large.

e. Fast reactions have equilibrium constants > 1.

f. Increasing the concentration of a reactant always increases the rate of a reaction.

Consider the following energy diagram for the conversion of A→G.

a. Which points on the graph correspond to transition states?

b. Which points on the graph correspond to reactive intermediates?

c. How many steps are present in the reaction mechanism?

d. Label each step of the mechanism as endothermic or exothermic.

e. Label the overall reaction as endothermic or exothermic.

Calculate Δ±á° for each oxidation reaction. Each equation is balanced as written; remember to take into account the coefficients in determining the number of bonds broken or formed.
