Consider the carbon dioxide gas, co2 (m = 44g/mol), at a temperature of 300k.
[note: use ms excel or a similar program].
a. for this gas, prepare a graph of f (v) (maxwell's velocity distribution)
boltzmann) vs v (speed). *** explain how you did the graph in excel***
b. calculate the quotient f (200.0 ms-1) /f(10.0 ms-1). what is the physical meaning of this quotient?
how would this quotient change if the temperature decreases?
c. calculate the fraction of molecules traveling at speeds between 200m/s and 250m/s. for this one
calculation, approximate the integral numerically, first with a single rectangle and then with two
rectangles, so you can calculate the height of each rectangle at the midpoint of your base.
