List I | List II |
\[Zn|Z{{n}^{2+}}(0.01M)|\,\]\[|Z{{n}^{2+}}(0.1M)|Zn\] | (p) primary cell |
1 Coulomb | (q) Secondary cell |
Dry Cell | (r) \[6.24\times {{10}^{18}}\]electrons |
Lead storage cell | (s) Concentration cell |
A) A-s, B-r, C-p, D-q
B) A-p, B-q, C-r, D-s
C) A-q, B-r, C-s, D-p
D) A-s, B-p, C-q, D-r
Correct Answer: A
Solution :
[a] |
[a] is concentration cell. |
[b] \[1{{e}^{-}}=1.6\times {{10}^{-19}}\] colulomb |
1 coulomb \[=\frac{{{10}^{19}}}{1.6}=6.24\times {{10}^{18}}\] |
[c] Dry cell is a primary cell. |
[d] Lead storage cell is secondary cell. |
