6 moles of an ideal gas expand isothermally and reversibly from a volume of 1 litre to a volume of 10 litres at $2 7^{\circ} C$ . What is the maximum work done?

Options:

Answer:

Solution:

$W = - 2.303 nRT lo g \frac{V _{2}}{V _{1}}$ Given $n = 6, T = 2 7^{\circ} C = 273 + 27 = 300 K$ $V_{1} = 1 L, V_{2} = 10 L$ $∴ W = - 2.303 \times 6 \times 8.314 \times 300 lo g \frac{10}{1}$ $= 34.465 kJ$
