Generate a graph from the following data (using excel) and determine the following parameters from the graph: exchange current, rate constant, charge transfer resistance and limiting current.
η(overpotential) (mV): -100, -120, -150, -500, -600
i (μA) : 45.9, 62.6, 100, 965, 965
First we have to plot it.

By analyzing the equation y=-0.4771x - 89.929 we can determine
the exchange current by setting y=0. So we have i0 =
-188.49 uA. Rate constant is the slope : -0.477 mV/uA. The charge
transfer resistance is related this way:
where F is Faraday's constant, R is the constant for gases, n is
the number of electrons involved and T the temperature. In this
case we find that
. You have to complete with the missing values.

You obtained the following
graphical data from two experimental runs to determine the freezing
point depression constant for a pure solvent. The solution was made
up by adding 3.025 g of naphthalene, C10H8,
to 45.320 g of pure solvent.
1.What is the freezing point temperature of the pure solvent (in
oC)?
2.What is the solution freezing point temperature (in
oC)?
3.What is the freezing point depression, Tfp (in
oC)?
4.What is the molar mass of naphthalene (in g/mol)?
5.How many...
This Excel file Undergrad Survey shows the data resulting from a survey of 50 undergraduate students at Clemson University. Majors of students in the survey are accounting (A), economics and finance (EF), management (M), marketing (MR), computer information systems (IS), other (O), and undecided (UN). "Number of affiliations" is the number of social networking sites at which the student is registered; "Spending" is the amount spent on textbooks for the current semester. The other variables are self-explanatory. We will assume...
