The viscosity ("thickness" as in honey vs. water, y measured in mPa·s) of ether is recorded in the CRC Handbook as a function of temperature (x, absolute temperature measured in [K]elvin). I assume accuracy of the tabulated viscosity is 1%. Many thermodynamic properties follow an Arrhenius relationship:

Y = Y_∞ exp(-E/(kT))

where E is the excitation energy, k is Boltzmann's constant, and T is the absolute temperature.

1. Fit this data to an Arrhenius relationship:

   y = A exp(B/x)

2. Consider the scientific claim of an Arrhenius relationship. Does this evidence (data) confirm or contradict this claim? Support your answer quantitatively.
3. Properly report (sigfigs, error, units) the A and B parameters of the best-fit function.
4. Connecting the fit equation to Arrhenius's theory requires:

   E = -Bk

   Boltzmann's constant, k, has the value: 1.3807 × 10^-23 J/K. Use a spreadsheet to calculate the excitation energy from B, and properly report (sigfigs, error, units) the value.

5. Self-document the spreadsheet and turn in a hardcopy of the page.
6. Make a hardcopy plot of the data with best-fit curve. Make an additional hardcopy plot with scales chosen so as to linearize the curve.
