2) A cold pack consists of an inner pouch containing ammonium nitrate, NH4 NO3 (s), and an outer pouch of water. Twisting the pack breaks the inner pouch and allows the water and ammonium nitrate to mix. As the ammonium nitrate dissolves, the temperature of the surroundings decreases. The energy change per mole of ammonium nitrate disso- ciated is 25.7 kJ. a) Classify the reaction as endothermic or exothermic. b) Draw a potential energy diagram for the reaction. Label the change in enthalpy. c) Write a thermochemical equation for this reaction.

2) A cold pack consists of an inner pouch containing ammonium nitrate,
NH4 NO3 (s), and an outer pouch of water. Twisting the pack breaks
the inner pouch and allows the water and ammonium nitrate to mix. As
the ammonium nitrate dissolves, the temperature of the surroundings
decreases. The energy change per mole of ammonium nitrate disso-
ciated is 25-7 kJ.
a) Classify the reaction as endothermic or exothermic.
b) Draw a potential energy diagram for the reaction. Label the change in
enthalpy.
c) Write a thermochemical equation for this reaction.
