2 "mole" N(2) and 3 "mole" H(2) gas are ...

`2 "mole" N_(2)` and `3 "mole" H_(2)` gas are allowed to react in a `20 L` flask at `400 K` and after complete conversion of `H_(2)` into `NH_(3)`. `10 L H_(2)O` was added and temperature reduced to `300 K`. Pressure of the gas after reaction is :
`N_(2)+3H_(2)to2NH_(3)`

A

`3Rxx300//20`

B
