Molecular flux-thermodynamic kinetics

In summary, the conversation discusses the thermodynamic kinetics of molecular flux in a system where a volume is divided into two equal parts by a partition. The number of white atoms on each side of the partition at a given time t can be calculated using the equation N=Noe^(vAt/4V) where n=N/V and Phi= dN/dAdt. The accuracy of this equation is checked for t-->infinity and t-->0. The impact of having a free space in the right volume is also discussed.

Molecular flux--thermodynamic kinetics

Homework Statement



A volume is divided into two equal parts by a partition. The left volume has N atoms. The atoms have a mass m. A hole of area A is made in the partition at time t=0

A)Develop an expression for the number of white atoms on each side of the partition at time t.
B)Check your answer when t-->infinity and when t-->0
C) If the right volume is just free space how is your answer changed?



Homework Equations



[itex]\Phi[/itex]=[itex]\Delta[/itex]/[itex]\Delta[/itex][itex]A[/itex]
*[itex]\Delta[/itex]t

Phi= 1/4(v)n where n=N/V

The Attempt at a Solution



i got N=Noe^(vAt/4V) my teacher says this is wrong if i take t-->infinity...im pretty sure what i solved for is correct tho...
