One mole of an ideal gas at `25^(@)C` is subjected to expand reversible ten times of its intial volume. The change in entropy of expansion is

Explanation

We have, `DeltaS = (q_(1))/(T) = (2.303nRT"log"_(10)(V_(2))/(V_(1)))/(T)`
Given, `n=1, R = 8.314J, T = 298K, V_(1) = V, V_(2) = 10V`
`:. DeltaS = 2.303 xx1 xx 8.314 "log"_(10)(10V)/(V)`
`= 19.15 J K^(-1) mol^(-1)`
