	Differential Data Analysis: http://www.youtube.com/watch?v=-O2JGXD9emE Comments: Deterimines the rate law parameters k and reaction order using averages between data points rather than equal area differentiation. The rate given near the end of the video should be -ra rather than r.
	Batch Reactor Data Analysis: http://www.youtube.com/watch?v=fM8EJjn6Xp8 Comments: The analysis uses Excel to determine ( -dCa/dt ) and then plots it against Ca to determine the rate constant.
	Least Squares Method: http://www.youtube.com/watch?v=yVkpq20OtcE Comments: Uses Excel and Polymath
	Non-linear Regression - an Introduction: http://www.youtube.com/watch?v=G5JZsVjCYbY Comments: Still the same problem with rate definition in terms of r rather than -ra. The rate MUST be defined with respect to a specific species. Just replace r with -ra everywhere and you will be fine. Otherwise, good example.
	Non-linear Regression Using Polymath: http://www.youtube.com/watch?v=1hbPaI7op-4 Comments: Video shows how to insert the numbers and model equations in Polymath to determine the rate constant and reaction order.
