A flask of 1L having NH(3)(g) at 2.0atm ...

A flask of `1L` having `NH_(3)(g)` at `2.0atm` and `200K` is connected with the another flask of volume `800 mL` having `HCI(g)` at `8atm` and `200K` through a narrow tube of negligible volume. The two gases react to form `NH_(4)(CI(s)` with evolution of `43kJ mol^(-1)` heat. if heat capacity of `HCI(g)` at constant volume is `20 JK^(-1) mol^(-1)` and neglecting heat capacity of flask, `NH_(4)CI`, and volume of solid `NH_(4)CI` formed, calculated in the flasks, produced, final temperature, and final pressure in the flasks. (Assume `R = 0.08 L atm K^(-1) mol^(-1))`
