What is the total pressure at equilibrium in vessel V2?
Options:
Answer:
A
Solution:
Each gas initially has 138/(34+62+2+40) = 1 mol. Equilibrium diphosphorus is 77.5/62 = 1.25 mol, so the reaction extent is 0.25 mol.
The equilibrium amounts of phosphine, diphosphorus, hydrogen and argon are 0.50, 1.25, 1.75 and 1 mol; total amount is 4.50 mol.
243 = [(1.25)(1.75)3/(0.50)2](P/4.50)2.
P = √((243×4.52)/[4×1.25×1.753]) atm, option (a).
