Chemistry - Electrochemistry Question with Solution | TestHub

To decompose 1 mole of${\text{H}}_{\text{2}}\text{O,}$we need two moles of electrons. To decompose 4 moles of${\text{H}}_{\text{2}}\text{O,}$we need 8 Faraday.
Now,$\text{Q}\text{=}\text{I}\text{×}\text{t}$
$\Rightarrow \text{t}=\frac{8\times 96500}{4}$
$=1.93\times {10}^5\text{sec}$
