Smelling salts, sometimes used to revive a groggy or unconscious person, are made of ammonium carbonate. The equation for the endothermic decomposition of ammonium carbonate is
(NH4)2 CO3 (s) <=> 2NH3 (g) + CO2 (g) + H2O
Would you expect smelling salts to work as well on a cold winter day as on a warm summer day? Explain your answer.
