Suppose we have a dual flask system with eight molecules in it. The specific molecules are numbered 1 to 8. Two of the possible arrangements of the molecules are shown in the figure
A (picture shows 4 molecules in each flask with 5, 7, 8, and 4 in the left and 1 2 3 and 6 in the other)
A (picture shows 4 molecules in each flask with 5, 7, 8, and 4 in the left and 1 2 3 and 6 in the other)
B (picture is the same flask system but only 4 is in the left flask while the other molecules occupy the other one)
a. In which of the two arrangements, if either, is more probable than the other?
b. is your answer in part A consistent with our expectation that the gas molecules, on average, distribute themselves equally between two flasks? Explain.
