Honors Reaction Rates

The graph in your notes present the sigma v as a function of temperature in KeV. Unfortunately they label the "sigma v" as "reaction rates". It would be the reaction rate if n = n2 =1 but it is not the reaction rate in our cases with our much, much higher n s.

It is a log log graph so it can show and enormous range of information. Each little tick is an increase of 1 x the quantity listed below the tick. In other words the first tick above 10^-22 means the sigma v is 2 x10^-22. At 20 KeV ( one tick to the right of 10 KeV, the sigma v is about 7x10^-22.

Hope this helps.
