Decomposition of ammonium chloride is an endothermic reaction. The equilibrium may be represented as:
`NH_(4)Cl(s) hArr NH_(3)(g)+HCl(g)`
A `6.250 g` sample of `NH_(4)Cl` os placed in an evaculated `4.0 L` container at `27^(@)C`. After equilibrium the total pressure inside the container is `0.820` bar and some solid remains in the container. Answer the followings
The value of `K_(p)` for the reaction at `300 K` is
