Antoine equation

The Antoine equation relates the vapor pressure of a pure liquid to the temperature according to this equation:

\(\log_{10} P(T) = A + B / (T + C)\)

Use this data to find values for \(A, B, C\) and confidence intervals for each parameter.

import numpy as np

TC = np.array([-36.7, -19.6, -11.5, -2.6, 7.6, 15.4, 26.1, 42.2, 60.6, 80.1])  # Temp in degC
P = np.array([1, 5, 10, 20, 40, 60, 100, 200, 400, 760])  # vapor pressure in Torr

Part 2

Plot the data, and your fit over the temperature range of -50 to 100 degC.
