A container of volume 1*10^-5 cm^3 holds three molecules of gas b, which we label b1, b2, and b3. In 1 second, there are two b1-b2 collisons, two b1-b3 collisions, and two b2-b3 collisons.
(a) find zb(b)
(b) fin Zbb, without using the result for zb(b)
is Zbb equal to Nbzb(b) / V?
Is Zbb equal to 0.5 NbZb(b) / V ?
