Homework Help: Mixture of ideal gas (a tricky one?)

  1. Sep 5, 2010 #1
    1. The problem statement, all variables and given/known data

    ethylene is stored in 5.6 liter spherical vessel at 260degC and 2750 kPa. To protect against explosion the vessel is enclosed in another spherical vessel with volume of 56L and filled with nitrogen at 260degC and 10.1Mpa. The entire assembly is maintained at 260degC in a furnace. The inner vessel raptures/ruptures. Determine the final pressure and the entropy change

    2. Relevant equations

    just give me a clue where to start i think i will be able to solve it. but i will appreciate if you answer it.

    3. The attempt at a solution

    of course i tried to use the ideal gas equation. and i think, from my understanding, rupture means it expands. so correct me if im wrong. by the way i have the final answers: P=9365kPa and 0.1671kJ/K
