A reaction is carried out in a cylinder fitted with a movable piston. The starting volume is V$=5\mathrm{.}00$L$,$ and the apparatus is held at constant temperature and pressure. Does V increase, decrease, or remain the same after reaction? Assume that $\backslash$Delta H$=35\mathrm{.}2$kJ

and $\backslash$Delta E$=35\mathrm{.}0$kJ

Then Calculate the final volume V$.$ Express your answer in liters to three significant figures.
