Question
The value of reaction quotient [Q], for the following cell
Zn(s)|Zn2+ (0.01 M)|| Ag+ (1.25 M | Ag (s) is
156
125
1.25 x 10-2
6.4 x 10-3
Solution
D.
6.4 x 10-3
The cell reaction is
Zn(s) → Zn2+ (0.01 M) + 2e-
[Ag+ (1.25 M) + e- → Ag (s)] x 2
________________________________________
Zn(s) + 2Ag+ (1.25 M) → Zn2+ (0.01 M) + 2Ag(s)
value of Q = 6.4 x 10-3
