Work (w) involved in isothermal reversible expansion from $\mathrm{V}_{\mathrm{i}}$ to $\mathrm{V}_{\mathrm{f}}$ of n moles of an ideal gas is
(a)$\mathrm{w}=-\mathrm{nRT} \ln \left(\mathrm{V}_{\mathrm{f}} / \mathrm{V}_{\mathrm{i}}\right)$
(b)$\mathrm{w}=\mathrm{nRT} \ln \left(\mathrm{V}_{\mathrm{f}} / \mathrm{V}_{\mathrm{i}}\right)$
