हिन्दीFor the reversible isothermal expansion of \( n \) moles of an ideal gas from volume \( V_i \) to \( V_f \), the work done by the system is given by:
Correct answer · Option 2
\( w_{\text{rev}} = -2.303\, nRT \log(\frac{V_f}{V_i}) \)
Explanation
For reversible isothermal expansion, \( w_{\text{rev}} = -\int p\, dV = -nRT \ln(V_f / V_i) = -2.303\, nRT \log(V_f / V_i) \).
