# Question: You have 2 4 moles of a gas contained in a

You have 2.4 moles of a gas contained in a 4.0-L bulb at a temperature of 32oC. This bulb is connected to a 20.0-L sealed, initially evacuated bulb via a valve. Assume the temperature remains constant.

a. What should happen to the gas when you open the valve? Calculate any changes of conditions.

b. Calculate ΔH, ΔE, q, and w for the process you described in part a.

c. Given your answer to part b, what is the driving force for the process?
