Equilibrium Question 721
Question: If in the reaction $ N_2O_4=2N{O_{2,}},a $ is that part of $ N_2O_4 $ which dissociates, then the number of moles at equilibrium will be
Options:
A) 3
B) 1
C) $ {{(1-a)}^{2}} $
D) $ {{(1+a)}^{2}} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \underset{\underset{(1-\alpha )}{\mathop{1}},}{\mathop{N_2O_4}},\rightarrow \underset{\underset{2\alpha }{\mathop{0}},}{\mathop{2NO_2}}, $ Total mole at equilibrium $ =(1-\alpha )+2a=1+\alpha $
