2X (g)+ Y(g) --> Z (g)
Ok,Q states that if stoichiometric quantities of X (g) and Y(g) are introduced into sealed,rigid container at constant tem with an initial pressure of 12 atm,what will the pressure in the container be when the reaction in complete?
a.12 atm
b.6 atm
c.4 atm
d.3 atm
e.2 atm
ok, I choose c simple b/c I thought when 3 mole=12 atm then 1 mole=4 atm
and apparently my reasoning was right BUT,then I was tempted to choose 12 atm simply b/c of wording,when it says sealed and rigid that means there is no interaction of gases with outside so I thought maybe the pressure will stay the same!!!
I mean I know that the first reasoning was right but I just want to know why they used sealed and rigid container there?does make any diffrence if we had open container!
Thank you.
