Solution: Expansion of a gas into an evacuated space is a spontaneous process.The reverse process-gas molecules initially distributed evenly in two flasks all moving into one flask-is not spontaneous.If flask B were smaller than flask A, would the final pressure after the stopcock is opened be greater than, equal to, or less than 0.5 atm?

Problem

A diagram shows two flasks, connected by a closed stopcock.  Flask A on the left has gas at 1 atmosphere, while flask B on the right is an evacuated flask at 0 atmospheres. When the stopcock opens, the gas expands to occupy both flasks.  Both flasks A and B now have 0.5 atmospheres of pressure; this process is spontaneous. A third diagram shows the stopcock still open, but all gas molecules have moved back into flask A. This process is not spontaneous.
