The number of correct statements among the following
1 The expansion work for a gas into vacuum is equal to zero.
2. 1 mole of a gas occupying 3 litre volume on expanding to 15 litre at constant pressure of 1 atm does expansion work 1.215kJ.
3. The maximum work done by the gas during reversible expansionof 16g `O_(2)` at 300K from `5dm^(3)` to `25dm^(3)` is 2.0074 kJ.
4. The `DeltaS "for " s rarr l` is almost negligible in comparison to `DeltaS` for `l rarr g`.
5. `DeltaS= 2.303 nR "log" (V_(2))/(V_(1))` (at constant T)
6. Reversible isothermal work done `= -2.303nRT "log"_(10) (V_(2))/(V_(1))`
