The dissolution of ammonium nitrate is given by the reaction: NH4NO3 (s) ----> NH4+ (aq) + NO3- (aq) Assuming that the values of ΔH° and ΔS° do not change appreciably with temperature, calculate the ΔG° value for the reaction from the polyatomic ion data in standard thermodynamic property tables. ΔG°: -4.1 kJ Predict the lowest temperature at which the reaction is spontaneous. T= _____ degrees Celsius

The dissolution of ammonium nitrate (NH4NO3) in water is a classic example of a solute that has an endothermic enthalphy of solution (ΔHsolution). What is (are) the "driving force" (driving forces) for the dissolution of NH4NO3? Formation of ion-dipole interactions only. Increasing entropy only. Formation of ion-dipole interactions and decreasing entropy. Formation of dispersion interactions and increasing entropy. Formation of dispersion interactions only

Activity #1: Dissolution of ammonium nitrate in water Fill a 100 ml beaker half-full with water. Place your hand on the outside of the beaker to gauge the temperature Add a large scoop of ammonium nitrate to the beaker and stir. Feel the temperature of the beaker as the ammonium nitrate dissolves. 1. Write the molecular and total ionic equations for the dissolution of ammonium nitrate.

There are a smallpackage of ammonium nitrate (NH4NO3) in water. When the inside bag is broken, the solute dissolves in the water. This dissolution requires energy and the water cools and freezes. I have done many experiments to find the best packs, and the market leader uses 300 g of the solute and 300 mL of water. It reaches a final temperature of -2 C. If I assume the dissolution processis so fast that it can be modelled as adiabatic,...

The decomposition of ammonium nitrate is first-order. NH4NO3 (aq) → N2O(g) + 2H2O(g) The rate constant of this reaction is 0.110 min-1. If the initial concentration of ammonium nitrate is 0.551 M, what is the concentration after 38.5 minutes?

Instant cold packs, often used to ice athletic injuries on the field, contain ammonium nitrate and water separated by a thin plastic divider. When the divider is broken, the ammonium nitrate dissolves according to the following endothermic reaction: NH4NO3(s)-->NH4 ^+(aq) + NO3^-(aq). In order to measure the enthalpy change for this reaction, 1.25 g of NH4NO3 is dissolved in enough water to make 25.0 mL of solution. The initial temperature is 25.8 degrees C and the final temperature (after the...
