Two mole of an ideal gas originally at a volume of `8` L at `1000` K , is allowed to expand adiabatically until final volume is `24` L . For the gas `C_(v) = 1.5R` . Calculate values of `DeltaS` for the process when:
`(i)` The expansion takes place reversibly.
`(ii)` The change in volume involves a free expansion.
Sum of `DeltaS` of these two case is _________.
(Used :`e^(1.09) = 3 ` and `1.09 xx 8.314=9)`
