MCQ
Initial $EMF$ of above cell at $298$ $K$ is .............. $\mathrm{V}$
- A$-0.059$
- ✓$0.059$
- C$0.59$
- D$0.0059$
✓
Answer
Correct option: B.
$0.059$
b
$\mathrm{E}=\frac{-0.059}{1} \log \frac{0.01}{0.10}=0.059\, \mathrm{V}$
$\mathrm{E}=\frac{-0.059}{1} \log \frac{0.01}{0.10}=0.059\, \mathrm{V}$
