The webassign question we did in class. Really did have a work factor. Solve for the number of moles use q was correct. There is a volume change assume all the moles convert to gas, using PV=nRt solve for the volume. Then plug back in for -PDV for work. Then solve for E Nov. 5, 2007 short review for test on Tues.
