Answer:

These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes. Melting solid salts. ... Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.

Explanation:

We have that an example of an endothermic reaction is given as

  • Evaporation
  • The Formation of Nitric Acid

From the question we are told

Which reaction is an example of an endothermic reaction?

Generally an endothermic reaction is a reaction where heat energy is absorb from the air in to a system.

Generally it cause a reduction in the temperature of a system and can be found in processes like

  • Evaporation
  • The Formation of Nitric Acid

Therefore

An example of an endothermic reaction is given as

  • Evaporation
  • The Formation of Nitric Acid
