Solution: Consider the apparatus shown in the drawing.When the valve between the two containers is opened and the gases allowed to mix, how does the volume occupied by the N2 gas change?

Problem

Consider the apparatus shown in the drawing

Two gas flasks are connected by a tube with a stopcock in the middle. N2 is in the flask on the left (2.0 liters, 1.0 atmospheres, 25 degrees C) and O2 is in the flask on the right (3.0 liters, 2.0 atmospheres, 25 degrees C)..

When the valve between the two containers is opened and the gases allowed to mix, how does the volume occupied by the N2 gas change?

Solution

We are asked to determine how the volume occupied by N2 gas change in the following apparatus:

Two gas flasks are connected by a tube with a stopcock in the middle. N2 is in the flask on the left (2.0 liters, 1.0 atmospheres, 25 degrees C) and O2 is in the flask on the right (3.0 liters, 2.0 atmospheres, 25 degrees C).
