Question

Work done by a system under isothermal change from a volume $V_1$ to $V_2$ for a gas which obeys Vander Waal's equation $(V-\beta n)\left(P+\frac{\alpha n^2}{V}\right)=n R T$

Accepted Answer

$n R T \log _e\left(\frac{V_2-n \beta}{V_1-n \beta}\right)+\alpha n^2\left(\frac{V_1-V_2}{V_1 V_2}\right)$

Answer

$n R T \log _{10}\left(\frac{V_2-\alpha \beta}{V_1-\alpha \beta}\right)+\alpha n^2\left(\frac{V_1-V_2}{V_1 V_2}\right)$

Answer

$n R T \log _e\left(\frac{V_2-n \alpha}{V_1-n \alpha}\right)+\beta n^2\left(\frac{V_1-V_2}{V_1 V_2}\right)$

Answer

$n R T \log _e\left(\frac{V_1-n \beta}{V_2-n \beta}\right)+\alpha n^2\left(\frac{V_1 V_2}{V_1-V_2}\right)$
