What is the heat of reaction for dissolving NH4NO3?
The cold pack is activated and applied to the affected area. As the ammonium nitrate dissolves, it absorbs heat from the body and helps to limit swelling. For ammonium nitrate, ΔHsoln=25.7kJ/mol.
What is the molar enthalpy of NH4NO3?
Selected ATcT enthalpy of formation based on version 1.118 of the Thermochemical Network

| Ammonium nitrate | (NH4)NO3 (cr,l) | -365.22 |
What is the entropy of ammonium nitrate?
The standard entropy S of aqueous ammonium nitrate is 260J/K*mol.
What happens when NH4NO3 is dissolved in water?
If you gently heat ammonium nitrate that has dissolved in water, the solution breaks down to release nitrous oxide, commonly called laughing gas.
What is heat of dissociation?
Definition of heat of dissociation : the heat of reaction resulting from dissociation of molecules of a compound into smaller molecules, fragments, or atoms.
How do you calculate the specific heat of a solution?
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .
Is the dissolution of ammonium nitrate endothermic or exothermic?
endothermic reaction
Ammonium nitrate dissolving in solution is an endothermic reaction. As the ammonium nitrate dissolves, heat energy is absorbed from the environment causing the surrounding environment to feel cold.
Why is the dissolution of ammonium nitrate spontaneous?
The dissolution of ammonium nitrate in water is a spontaneous endothermic process. It is spontaneous because the system undergoes a decrease in entropy: decrease in enthalpy: an increase in entropy an increase in enthalpy: We don’t have your requested question, but here is a suggested video that might help.
Why does NH4NO3 dissolved in water spontaneously?
Ammonium nitrate (NH4NO3) ( N H 4 N O 3 ) dissolves readily in water even though the dissolution is endothermic by 26.4 kJ/mol. The solution process is spontaneous because: a. of the increase in disorder upon dissolution of this strong electrolyte.
When nh4no3 is dissolved in water the temperature of the water decreases?
When NH4NO3 is dissolved in water, the temperature of the water decreases. When NaOH is dissolved in a separate water sample, the temperature of the water increases. Based on these observations, it can be concluded that the dissolving of? NH4NO3 is endothermic and the dissolving of NaOH is exothermic.
When NH4NO3 is dissolved in water the temperature of the water decreases?
