Question 1
1.
Question 2
2.
Given the following system at equilibrium:
The addition of Cl
-
 ions will cause the concentration of Ag
+
(aq) to
Decrease as the amount of AgCl(s) decreases
Decrease as the amount of AgCl(s) increases
Increase as the amount of AgCl(s) decreases
Increase as the amount of AgCl(s) increases
Question 3
3.
Given the following system at equilibrium:
Increasing the concentration of N
2
(g) will increase the forward reaction rate due to:
