A flask contains `NH_4Cl(s)` in equilibrium with its decomposition products.
`NH_(4)Cl (s) Leftrightarrow NH_(3)(g)+HCl(g)`
For this reaction, `triangleH=` 176 kJ/mole. How is the mass of `NH_3` in the flask affected by each of the following disturbances?
(a) The temperature is decreased
(b) `NH_3` is added
(c) HCl is added
(d) `NH_4Cl` is added with no appreciable change in volume
(e) A large amount of `NH_4Cl` is added decreasing the volume available to the gases.
