Here's the chemical equation for the reaction:
NH₄Cl(s) → NH₃(g) + HCl(g)
The reaction is reversible, meaning that the ammonia and hydrogen chloride can recombine to form ammonium chloride again if the temperature is lowered.
It's important to note that this decomposition process is endothermic, meaning it requires heat energy to occur. The heat causes the ammonium chloride molecules to break apart into their constituent gases.
