Question

If 10 moles of an ideal gas expands reversibly and isothermally from 10 L to 100 L at 300 K, then entropy change will be 

(a) -19147. JK^-1 mol^-1 

(b) 191.24 JK^-1 

(c) 83.03 JK^-1 

(d) 83.03 JK^-1 mol^-1

Answer 1

Correct option: (a) -19147. JK^-1 mol^-1

Given,V₂ = 100 L,

V₁ = 10 L
