* Tutorial | Linear Fit to your data in Excel, includes use of basic plotting options.
00:00 -- Intro
00:36 -- Integrated rate law equations
01:07 -- Zeroth Order test
01:52 -- Add Trend-Line (0th order test)
03:52 -- Compare Linear vs Exponential (r^2)
04:25 -- First Order test
07:31 -- Second Order test
08:59 -- Trend Line: Exp vs Linear (2nd order test)
09:54 -- Conclusion: Analysis of results
10:49 -- Final Suggestions: Formatting plots
We use a General Chemistry Kinetics problem: Determine Order of Reaction; but Linear Regression can be worked out similarly for other data sets.
NOTE I am using r^2 (correlation coefficient) Very Loosely here. For textbook problems this may be ok since we have "model" data, and differences in plots are rather evident. You definitely would like to check other statistics tools (e.g., Residuals plots, Runs, etc.) for more complicated problems.
