Equilibrium Question 619
Question: If in the reaction $ N_2O_4=2NO_2,,\alpha $ is that part of $ N_2O_4 $ which dissociates, then the number of moles at equilibrium will be [MP PET 1990; MH CET 2001; KCET 2005]
Options:
A) 3
B) 1
C) $ {{(1-\alpha )}^{2}} $
D) $ (1+\alpha ) $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \underset{(1-\alpha )}{\mathop{\underset{1}{\mathop{N_2O_4}},}}, $ ⇌ $ \underset{2,\alpha }{\mathop{\underset{0}{\mathop{2NO_2}},}}, $ total mole at equilibrium $ =(1-\alpha )+2\alpha $
$ =1+\alpha $
