A cylinder of volume V liters at 250 K is pressurized with 0.684 bar of N2(g). A second cylinder of size 2V liters, also at 250 K, is pressurized with 0.924 bar of H2(g). The cylinders are connected (assume the connecting hardware has a negligible volume), and then heated to 400 K. Once at 400 K, the valve separating the
cylinders is opened, where the gases mix and react according to

N2(8) + 3 Ha(g) -> 2 NH3(g)

If the total pressure in is observed to be 1.243 bar, what is the mole fraction of NH3?

Hi louist

There's a lot being asked here for a multiple choice question. What have you done so far? Did you professor do any examples in class similar to this one that you can provide as reference?

I looked through my notes, and the closest thing I could find related to my own studies is this example: https://biology-forums.com/index.php?topic=1999578.0

Does that help?
