o is watching the event it would appear that the two molecules never really did collide but
passed through one another instead!
If we denote by M,,
the rate of transfer of momentum from the component 1 molecules to the
wall and by M,, the rate of transfer to component 2 molecules, the momentum balance equation for the component 1 molecules becomes I
M,,
+ M,, = -Tr:(dp,/dz)
dz , i
and a similar equation can likewise be written for component 2.
