Question

The dissolution of ammonium nitrate in water is given by the following equation:

NH4NO3(s) + heat → NH4+(aq) + NO3-(aq)

Which statement best describes what an energy graph of this reaction would look like?

(1 point)

The reactants and products would appear at a high energy state.

The reactants would appear at a lower energy state than the products.

The reactants and products would appear at a low energy state.

The reactants would appear at a higher energy state than the products.

Answer 1

The reactants would appear at a lower energy state than the products.

Explanation: Dissolving NH4NO3 is endothermic (it absorbs heat), so the products have higher enthalpy (energy) than the reactants.
