A flask of `4.48 L` capacity contains a mixture of `N_(2)` and `H_(2)` at `0^(@)C` and `1 atm` pressure. If thed mixture is made to react to form `NH_(3)` gas at the same temperature, the pressure in the flask reduces to `0.75 atm`. Select statement(s) :A. Initially total moves of gases in the mixture is `0.2 mol`.B. Initially total moves of gases in the mixture is `0.4 mol`.C. The partial pressure of `NH_(3)` gas in the final mixture is `0.33 atm`.D. The partial pressure of `NH_(3)` gas in the final mixture is `0.25 atm`. |

Answer» Correct Answer - B::C `|{:(,,N_(2),+,3H_(2)rarr2NH_(3)),("Initally",a atm, b atm,0,),("Finally",a-x,,b-3x,2x):}|` `:. a + b = 1` and `a + b - 2x = 0.75` `:. P_(NH_(3)) = 2x = 0.25 atm` |
