kinetics
what do enzymes do
lower the activation energy of a reaction
charge of hydrogen ion?
H+
plating occurs on the...
anode or cathode?
cathode
define oxidation and reduction
OIL RIG
the pH of a solution is 4, what is the pOH?
is this solution acidic or basic?
14-4 = 10
acidic (pH <7)
how do catalysts affect equilibrium
they do not !!!
charge of Fluoride ion?
F-
what is the equation that relates ∆Gº and Eºcell
∆Gº = -nFEºcell
2H2O --> 2H2 + 2O2
what is oxidized, what is reduced?
H reduced
O oxidized
7.4
Daily double, for 600:
give the basic equation/a sample equation for a rate law
How do you know what goes into the rate law?
rate = k [A]^x [B]^ y
you know what goes in from experimentation
Charge of Mg?
Mg2+
what is a Faraday?
the charge on one mole of electrons, 96,485 C
What is being oxidized?
4Fe + 3O2 --> 2Fe2O3
Fe
what is a buffer?
(components not function)
a mixture of a weak acid & its salt
OR a weak base and its salt
how do you determine the order of a reaction?/what is the reaction order?
add up order of each reactant -- order of reactants are determined
eg if rate law is rate= k[A][B] it is a second order reaction
Charge of silver ion?
Ag+
which kind of electrochemical cell is used for non-spontaneous reactions
electrolytic
CuSO4 + Zn --> Cu + ZnSO4
what is the reducing agent
reducing agent = being oxidized
Zn
equation that relates pH and pKa
pH = pKa + log(base/acid)
what is collision theory?
the rate of a reaction is proportional to the number of collisions per second between reacting molecules
charge of zinc ion?
Zn2+
name the 3 kinds of electrochemical cells
galvanic/voltaic
concentration
electrolytic
daily double, for 1000:
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
what is the oxidation number of each element?
what are the oxidizing and reducing agents?
0,+1,-2 0 --> +3,-2 +1,-2
carbon is oxidized, reducing agent
oxygen is reduced, oxidizing agent
what is the pKa of an acid?
half way to EP, pH at which half of the molecules are in acid form, half are in base form
