2 mole of an ideal gas at 27 o C temperature is expanded reversibly from 2 L to 20 L. Find the entropy change R = 2 Calmol − 1 K -1

Question

2 mole of an ideal gas at 27 o C temperature is expanded reversibly from 2 L to 20 L. Find the entropy change R = 2 Calmol − 1 K -1, 92.1, 0, 4, 9.2

For isothermal reversible expansion -w = q = n R T × 2.303 log ⁡ v 2 v 1 = 2 R T × 2.303 log ⁡ 20 2 = 2 × 2 × T × 2.303 × 1 = 9.2 T Entropy change, S = q T = 9.2 T T = 9.2 Cal K − 1
