MCQ
What is the work done when $1\, mole$ of a gas expands isothermally and reversibly from $25\, L$ to $250\, L$ at a temperature of $300\, K$?....$J$
- A$-3542$
- ✓$-5744$
- C$-2657$
- D$-4890$
✓
Answer
Correct option: B.
$-5744$
b
$ \mathrm{w} =-2.303 \times 1 \times 8.314 \times 300 \log \frac{250}{25} $
$ \mathrm{w} =-2.303 \times 1 \times 8.314 \times 300 \log \frac{250}{25} $
$=-5744 \,\mathrm{J}$
