MCQ
How much time is required for complete decomposition of two mole $H_2O$ using $4\,ampere$ ............. $\mathrm{s}$
- A$3.86\times 10^5$
- B$1.93\times 10^5$
- ✓$96500$
- D$48250$
✓
Answer
Correct option: C.
$96500$
c
$\mathrm{H}_{2} \mathrm{O}_{(1)} \rightarrow \mathrm{H}_{2}(\mathrm{aq})+\frac{1}{2} \mathrm{O}_{2}$
$\mathrm{H}_{2} \mathrm{O}_{(1)} \rightarrow \mathrm{H}_{2}(\mathrm{aq})+\frac{1}{2} \mathrm{O}_{2}$
$2 \times 2=\frac{4 \times t}{96500}$
$\mathrm{t}=96500 \mathrm{sec}$
Hence, option $\mathrm{C}$ is correct
