Velocity calculated for (C [i + 1] + C [i]) / 2 and not Ci as in the movie, to use "Central difference". This small modification greatly improves the quality of the results. C = 0.4655, 0.3905, 0.31, 0.245 resulting in y = 2,0366 x -8,4279 So the phrase "crude method..." etc. is not for take into account. The derivative of a cubic spline give almost the same result.

why the slope is not k?
r=kC^n
ln(r)=ln(k)+n*ln(C)
so the slope in ln(r) vs. ln(C) is n and k=exp(intercept)
@@FilipeFreireGama units of Cc &CA !?!?
What are units of Cc @CA
Cc and CA can be in mol/L for instance, its not important because k will allways have compatible units to r have correct units.
