Reaction involved in present electrochemical cell,
At Anode: Zn → Zn^2+ + 2e^2-
At cathode: Zn^2+ + 2e^2- → Zn
Net Reaction: Zn + Zn^2+ ('x' m) → Zn^2+(0.1 m) + Zn
Number of electrons involved in present electrochemical cell = n = 2
According to Nernst equation for electrochemical cell,
Ecell = -2.303
![\frac{RT}{nT} log \frac{[Zn^2+]R}{[Zn^2+]L}](https://tex.z-dn.net/?f=%20%5Cfrac%7BRT%7D%7BnT%7D%20log%20%20%5Cfrac%7B%5BZn%5E2%2B%5DR%7D%7B%5BZn%5E2%2B%5DL%7D%20%20)
= 0.014
Given: T =

, F = 96500 C, R = gas constant = 8.314J/K.mol, [Zn^2+]R = 0.1 m , Ecell = 0.014 v
∴ 0.014 = - 2.303

∴ log

=

= -2.1117
∴ log x = log(0.1) + 2.1117
∴x = 13.09 m

Non-renewable energy sources CAN EVENTUALLY BE USED UP.
Non renewable energy sources refer to those energy sources that can not be replenished. Once they are used up, new one can not be formed or produced, this is because they can only be formed by natural processes and these processes take millions of years to occur. Examples of non renewable energy sources are: coal, natural gas and oil. All the fuels obtained from fossils are non renewable in nature.
