For an isothermal reversible expansion process, the value of q can be calculated by the expression
(a) \( \mathrm{q}=2.303 \mathrm{nRT} \log \frac{\mathrm{V}_{2}}{\mathrm{~V}_{1}} \)
(b) \( \mathrm{q}=-2.303 \mathrm{nRT} \log \frac{\mathrm{V}_{2}}{\mathrm{~V}_{1}} \)
(c) \( \mathrm{q}=-\mathrm{P}_{\exp } \mathrm{nRT} \log \frac{\mathrm{V}_{1}}{\mathrm{~V}_{2}} \)
(d) None of these
\( \mathrm{P} \)
