A box with a membrane down the midddle has 20 N2 moelecules onone side and 50 o2 moelecules on the other side.
A) Once the membrane is broken how many molecules of N2 and ofo2 on average occupy half of the box?
B. Calculated the probility of finding all the nitrogen andoxygen moleculus simultaneously in the original columes
C) Calculate the change in entropy once the membrane is broken.
