Question

Experiments have shown the average frequency of chirp-ing of individual snowy tree crickets (Oecanthus fultoni) to be 178 min-1 at 25.0oC, 126 min-1 at 20.3oC, and 100. min-1 at 17.3oC.
a. What is the apparent activation energy of the reaction that controls the chirping?
b. What chirping rate would be expected at 15.0oC?
c. Compare the observed rates and your calculated rate from part b to the rule of thumb that the Fahrenheit temperature is 42 plus 0.80 times the number of chirps in 15 s.
