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
Given the following system at equilibrium:
Increasing the concentration of N
2
(g) will increase the forward reaction rate due to:
A decrease in the number of effective collisions
An increase in the number of effective collisions
A decrease in the activation energy
An increase in the activation energy
