Question

Two moles of a gas expand reversibly and isothermally at temperature of 300 K . Initial volume of the gas is 1 L while the final pressure is 4 .926 atm . The work done by gas is, -11488.28 J, -15036.28 J, -22488.28 J, -33488.28 J

To calculate final volume V 2 = n × R × T P 2 V 2 = 2 × 0.0821 × 300 4.926 = 10 L Now, V 1 = 1 L , V 2 = 10 L, T = 300 K, n = 2 mole W = − 2.303 nRT log V 2 V 1 = - 2.303 × 2 × 8.314 × 300 × log ⁡ 10 1 = - 11488.28 J
