Answer:
the answer is 2.75 but since that isn't an option I'd go with 1 because I just took a test with this question and it was the right answer.. hopefully that helps
Answer: The value of 
is 2
Explanation:
Moles of 
= 1.0 mole
Volume of solution = 1.00 L
Initial concentration of = 
Equilibrium concentration of 
=
The given balanced equilibrium reaction is,
Initial conc. 1.0 M 0 M
At eqm. conc. (1.0-x) M (2x) M
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)
Given : 2x = 1.0
x= 0.5
Now put all the given values in this expression, we get :
Thus the value of is 2
Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
