Question
How much time is required for complete decomposition of two mole $H_2O$ using $4\,ampere$ ............. $\mathrm{s}$

Answer

$\mathrm{H}_{2} \mathrm{O}_{(1)} \rightarrow \mathrm{H}_{2}(\mathrm{aq})+\frac{1}{2} \mathrm{O}_{2}$

$2 \times 2=\frac{4 \times t}{96500}$

$\mathrm{t}=96500 \mathrm{sec}$

Hence, option $\mathrm{C}$ is correct
