Question
Write the equation for the action of heat on:
(i) Ammonium chloride
(ii) Ammonium nitrate
State whether each reaction is an example of thermal dissociation or thermal decomposition.
Solution
(i) Action of heat on ammonium chloride is reversible. When heated, it decomposes to form ammonia and hydrogen chloride. When the products are cooled, they recombine to form ammonium chloride .
NH4CI
This is therm a I di ssoci a ti on reaction .
(ii ) Ammonium ni trate on heating completely disappears, escaping in the form of water vapour and ni trous oxide.
Nh4
This is therm a I di ssoci a ti on reaction .
