Question

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 extent of decomposition can be increased by
A. Increasing the temperature
B. Decreasing the temperature
C. Adding more `NH_(4)Cl`
D. Removing HCl(g)

Answer 1

Correct Answer - A
Since, the decomposition is an endothermic process hence on increasing temperature the equilibrium shift in forward direction.
