Equilibrium Question 725

Question: ‘a’ moles of $ PCl_5 $ , undergoes, thermal dissociation as: $ PCl_5 \leftrightharpoons PCl_3+Cl_2 $ , the mole fraction of $ PCl_3 $ at equilibrium is 0.25 and the total pressure is 2.0 atmosphere. The partial pressure of $ CI_2 $ at equilibrium is:

Options:

A) 2.5

B) 1.0

C) 0.5

D) None of these

Show Answer

Answer:

Correct Answer: C

Solution:

$ PCl_5\rightarrow PCl_3+Cl_2 $

$ at t=0 $ $ a $ $ 0 $ $ 0 $
$ t=tq $ $ a-x $ $ x $ $ x $

$ {P_{PCl_3}}={X_{PCl_3}}\times P_{T}=0.25\times 2=0.5atm $

$ {P_{PCl_3}}={P_{Cl_2}}=0.5atm $
