Which expansion will produce more change in entropy during reversible and isothermal process?A. `1 mol H_(2)` at `300K` from `2 L` to `20L`B. `1 mol N_(2)` at `400 K` from `1L` to `10L`C. `1mol O_(3)` at `500K` form `3L` to `30L`D. All have same `DeltaS` |
|
Answer» `DeltaS = 2.303 nR "log" (V_(2))/(V_(1))` `= 2.303 xx 1xx 8.314 log(10)` `= 19.15 J K^(-1) mol^(-1) ((V_(2))/(V_(1))=10 "for all")` |
